    2017-05-01

    This study is aimed at first introducing a well-known discrepant event; inseparable phone books and second, turning it into an experiment for high school or middle school students. This discrepant event could be used especially to indicate how friction force can be effective in producing an unexpected result. Demonstration, discussion, explanation and experiment steps are presented on how to turn a simple discrepant event into an instructional activity. Results showed the relationships between number of pages and force, as well as between amounts of interleave and force. In addition to these, the mathematical equation for the total force between all interleaved pages is derived. As a conclusion, this study demonstrated that not only can phone books be used, but also ordinary books, to investigate this discrepant event. This experiment can be conducted as an example to show the agreement between theoretical and experimental results along with the confounding variables. This discrepant event can be used to create a cognitive conflict in students’ minds about the concepts of ‘force and motion’ and ‘friction force’.

  2. Inseparability of science history and discovery

    Full Text Available Science is very much a logical progression through time. Progressing along a logical path of discovery is rather like following a path through the wilderness. Occasionally the path splits, presenting a choice; the correct logical interpretation leads to further progress, the wrong choice leads to confusion. By considering deeply the relevant science history, one might begin to recognize past faltering in the logical progression of observations and ideas and, perhaps then, to discover new, more precise understanding. The following specific examples of science faltering are described from a historical perspective: (1 Composition of the Earth's inner core; (2 Giant planet internal energy production; (3 Physical impossibility of Earth-core convection and Earth-mantle convection, and; (4 Thermonuclear ignition of stars. For each example, a revised logical progression is described, leading, respectively, to: (1 Understanding the endo-Earth's composition; (2 The concept of nuclear georeactor origin of geo- and planetary magnetic fields; (3 The invalidation and replacement of plate tectonics; and, (4 Understanding the basis for the observed distribution of luminous stars in galaxies. These revised logical progressions clearly show the inseparability of science history and discovery. A different and more fundamental approach to making scientific discoveries than the frequently discussed variants of the scientific method is this: An individual ponders and through tedious efforts arranges seemingly unrelated observations into a logical sequence in the mind so that causal relationships become evident and new understanding emerges, showing the path for new observations, for new experiments, for new theoretical considerations, and for new discoveries. Science history is rich in "seemingly unrelated observations" just waiting to be logically and causally related to reveal new discoveries.

    Program unity in Parque Prazeres - Campos dos Goytacazes, RJ, and the level of patient's knowledge about diabetes visual impairment. METHODS: Seventy two diabetic patients were selected, but only 46 attended the research. The patients were chosen based on Family's Health Program medical registers. They were submitted to visual acuity examination and afterward to a questionnaire in order to evaluate their knowledge level about visual impairment. Then, they were submitted to a direct fundoscopic examination. Statistical studies were done based on Microsoft Excel and Bioestat 5.0 RESULTS: Diabetic retinopathy prevalence was about 19,5% (CI 95% between 8,1 and 31%; 13% showed non proliferative diabetic retinopathy and 6,5% showed proliferative retinopathy. In accordance with World Health's Organization criteria: 8,5% were considered blind and 8,9% with low vision at the moment of ocular examination. Seventy two percent of patients had previous knowledge that diabetes could cause visual reduction, but 80% didn't know the necessary exams to diagnose it and 65% never were previously submitted to ophthalmoscopy. CONCLUSION: Blindness prevention programs by diabetic retinopathy in Family Health Programs are justified considering that the retinopathy diabetic prevalence in assisted communities could be high, as was in this study. The improvement of patient knowledge about the vision threatening risk and ophthalmological exams can allow a better retinopathy diabetic control.

  15. Inseparability of colours through dynamical breaking of SUsub(C)(3)

    International Nuclear Information System (INIS)

    Werle, J.

    1983-09-01

    A class of feasible quark field models based on the assumption that the quarks are the only carriers of colours is discussed. The forces between quarks are described by local but non-linear interaction between quark fields. Such models are much closer than QCD to the - so far very successful - naive quark model with colours. It is shown that inseparability and localization of colours, which are two basic conditions of quark confinement, are of dynamical nature. In particular, inseparability is simply incompatible with rigorous SUsub(C)(3) invariance. Therefore, explicit dynamical SUsub(C)(3) breaking is proposed in such a form that makes only the white currents strictly conserved. The resulting field equations imply manifest inseparability of colours. (author)

    1980-01-01

    The unity of the basic forces of Nature and the unity of all basic matter form the main theme of this paper. Recent developments in the theory of fundamental particles are reviewed. The 'quark' concept is described. Conclusion is drawn that the proton, neutron, hyperon and the sigma particles belong to one Baryon family. The Lepton family of electrons, muons and pions is also described. The quantum numbers isospin, strangeness etc. are explained. The nature of the four different basic forces viz., gravity, weak, electromagnetic and strong forces are discussed. Arguments are presented to indicate that the differences in these forces are described at low energies and that at high energies of the order of 10 5 BeV the three forces electromagnetic, weak and strong, merge into one and the same force and at the same energies quarks and leptons interact universally exhibiting their oneness. The stability of the proton is discussed. Future trends are indicated. A fundamental substructure 'preon' is proposed. (A.K.)

    A single or multiphase boost chopper regulator operating with unity power factor, for use such as to charge a battery is comprised of a power section for converting single or multiphase line energy into recharge energy including a rectifier (10), one inductor (L.sub.1) and one chopper (Q.sub.1) for each chopper phase for presenting a load (battery) with a current output, and duty cycle control means (16) for each chopper to control the average inductor current over each period of the chopper, and a sensing and control section including means (20) for sensing at least one load parameter, means (22) for producing a current command signal as a function of said parameter, means (26) for producing a feedback signal as a function of said current command signal and the average rectifier voltage output over each period of the chopper, means (28) for sensing current through said inductor, means (18) for comparing said feedback signal with said sensed current to produce, in response to a difference, a control signal applied to the duty cycle control means, whereby the average inductor current is proportionate to the average rectifier voltage output over each period of the chopper, and instantaneous line current is thereby maintained proportionate to the instantaneous line voltage, thus achieving a unity power factor. The boost chopper is comprised of a plurality of converters connected in parallel and operated in staggered phase. For optimal harmonic suppression, the duty cycles of the switching converters are evenly spaced, and by negative coupling between pairs 180.degree. out-of-phase, peak currents through the switches can be reduced while reducing the inductor size and mass.

  12. Gnosticism, church unity and the Nicene Creed

    Directory of Open Access Journals (Sweden)

    C. F.C. Coetzee

    2008-07-01

    Full Text Available Gnosticism (derived from the Greek word “gnosis; knowledge” is the well-known phenomenon or movement which dates from the first centuries of church history. The teaching of Gnosticism questioned and/or contradicted the teaching of the church on some of the fundamental truths of Scripture. Apart from Gnosticism, the Early Church also had to deal with the heresy of Arianism. In the Nicene Creed, formulated by the councils of Nicea (325 AD and Constantinople (381 AD the universal or catholic church responded officially to the heresies of both Gnosticism and Arianism. In the final edition of the Nicene Creed we also find an article on the unity, holiness, catholicity and apostolicity of the church. Both Gnosticism and Arianism posed a serious threat to the unity of the church.   In our times we experience a revival of ancient Gnosticism, both pagan and “Christian”. This revival is also called the New Age or the Age of Aquarius. Within the framework of this new worldview, we are witnessing a rediscovery of gnosis. The discovery and publication of certain ancient gnostic texts like the Nag Hammadi Codices, play a significant role in this revival. Consequently the canon of Scripture is questioned or openly rejected and also the creeds based on that Scripture.   The Nicene Creed played a major and decisive role in preserving and maintaining the unity of the church on the basis of the truth of Scripture. This age-old creed is today just as relevant and important in proclaiming and confessing the true faith and preserving the true unity of the church.

  13. Stopping power ratios less than unity?

    Science.gov (United States)

    Steinbeck, J.; Lucas, M. W.; Kemmler, J.; Groeneveld, K.-O.

    1990-03-01

    We present calculations of the stopping power ratio R for H2+ molecular ions incident on graphite. These calculations include contributions from both free valence electrons and bound core electrons. It is known from experiment [W. Brandt et al., Phys. Rev. Lett. 33 (1974) 1325; 35 (1975) 130] that R is greater than unity for ν > 1 (a.u.), although it can fall below unity at lower velocities [J.C. Eckhardt et al., J. Phys. C11 (1978) L851]. We predict, however, that in appropriately chosen conditions R can be less than unity for ν ⋍ 2, even though we have assumed the constituent protons to remain bare throughout the thin solid target so that this is not a charge state effect. We have used both pure and screened Coulomb potentials to describe the repulsion process of the two protons. We also compare our computations with the data of Steuer et al. [ IEEE Trans. Nucl. Sci. NS-30 (1983) 1069] for H2+ on graphite, ν = 4. Unfortunately, their interesting results for N2+ and O2+ are obtained at velocities which are too low for our th be appropriate.

On the one hand, globalization provided mainly by mass media, particularly by Internet and the on line electronic mail, will be scrutinized in relation to its psycholinguistic consequences: What are the differences that appear in human processing and how is the logical distinction between unity and diversity faced? How deep are the changes experienced by children, who are acquiring and learning their oral and written languages, using such media? On the other hand, despite globalization, the geometrical growth of science and technology brings with it a parallel lexical explosion: specific texts undermine the possibility of their comprehension by the outsider as if the text was written in a foreign language, and so, the unity of communication is broken and distortions may appear.

  15. Project UNITY: Cross Domain Visualization Collaboration

    Science.gov (United States)

    Moore, J.; Havig, P.

    UNITY is an International Cooperative Research and Development (ICR&D) project between the United States and Great Britain under the Research and Development Projects (RDP) Memorandum of Agreement (MOA). UNITYs objectives are to develop and evaluate the operational concepts and requirements for undertaking combined operations: a) pursuant to the interests of mission partners, b) develop, experiment, and demonstrate, transitionable emergent technologies, capabilities, or concepts, which facilitate the sharing of information and products between mission partners, and c) identify and define additional emerging technologies that may need to be developed to support current and future military information sharing. Collaboration between coalition partners is essentially for accurate and timely decision making in the ever increasing nature and tempo of global security. The purpose for this project is to develop engineering solutions in order to further investigate the human factors issues that arise while sharing information in a collaborative environment where security is an issue. The biggest difference between existing available solutions are in the presentation and interaction with the interface on both ends of the collaboration in order to preserve the expressed intent of shared situation awareness while also enabling markups and content on one screen that the other collaborator does not see and vice versa. The UNITY project stresses collaboration differently than all known realtime collaboration software in production, aka groupware, on the market today. The tradition of What You See Is What I See (WYSIWIS) as in typical implementations of shared whiteboards simply do not address the need for local and private information to be displayed in context with shareable data. This paper addresses the concerns, problems, and some solutions for shared 3D visualization and 2D tabular visualizations which are explored and presented within the space situation awareness problem

    Full Text Available Methicillin-resistant Staphylococcus aureus (MRSA is a major nosocomial pathogen worldwide. Malta is one of the countries with the highest MRSA prevalence in Europe, as identified from hospital blood cultures [1]. However, community prevalence of MRSA has never previously been investigated. This study aimed at establishing the prevalence of community MRSA nasal colonization in Maltese individuals and identifying the clonal characteristics of the detected isolates. Nasal swabs were collected from 329 healthy individuals who were also asked to complete a brief questionnaire about risk factors commonly associated with MRSA carriage and infection. The swabs were transported and enriched in a nutrient broth supplemented with NaCl. The presence of MRSA was then determined by culturing on MRSA Select chromogenic agar and then confirming by several assays, including catalase, coagulase and PBP2a agglutination tests. The isolates were assayed for antibiotic susceptibilities and typed by microarray analysis to determine the clonal characteristics of each strain. The prevalence of MRSA nasal colonization in the healthy Maltese population was found to be 8.81% (95% confidence interval [CI], 5.75–11.87%, much higher than that found in other studies carried out in several countries. No statistical association was found between MRSA carriage and demographics or risk factors; however, this was hindered by the small sample size. Almost all the isolates were fusidic-acid resistant. The majority were found to belong to a local endemic clone (CC5 which seems to be replacing the previously prevalent European clone UK-EMRSA-15 in the country. A new clone (CC50-MRSA-V was also characterized. The presence of such a significant community reservoir of MRSA increases the burdens already faced by the local healthcare system to control the MRSA epidemic. Colonization of MRSA in otherwise healthy individuals may represent a risk for endogenous infection and transmission to

This new approach is based on an evolutionary perspective of the European Union in which all that has already been achieved is used while the philosophy of the institutions and of the legal framework is reinterpreted by changing the accent of the European Union motto from “Unity in Diversity” to “Diversity in Unity”. The conclusion of the paper is that European Union needs to reconnect to its own realities and that, by accepting diversity in its existing unity rather than enforcing unity upon diversity, it can alleviate existing tensions, reconnect to citizens, restart innovation and creativity and find a better place in the global context.

    In the Space Station Processing Facility (SSPF), the Unity connecting module, part of the International Space Station, is lowered to its new location in the SSPF. In the background, visitors watch through a viewing window, part of the visitors tour at the Center. As the primary payload on mission STS-88, scheduled to launch Dec. 3, 1998, Unity will be mated to the Russian-built Zarya control module which should already be in orbit at that time. In the SSPF, Unity is undergoing testing such as the Pad Demonstration Test to verify the compatibility of the module with the Space Shuttle, as well as the ability of the astronauts to send and receive commands to Unity from the flight deck of the orbiter, and the common berthing mechanism to which other space station elements will dock. Unity is expected to be ready for installation into the Shuttle's payload canister on Oct. 25, and transported to Launch Pad 39-A on Oct. 27.

  7. Is there unity within the discipline?

    Newham, Roger A

    2012-07-01

    This paper will examine a claim that nursing is united by its moral stance. The claim is that there are moral constraints on nurses' actions as people practising nursing (nurses qua nurses) and that they are in some way different from both what for now can be called standard morality and also different from the person's own moral views who also happens to be a nurse, hence the defining and unifying factor for nursing. I will begin by situating the claim within the broader area about the need for a definition to state features that are essential to all and only members of its class. This will highlight the fact that there are two distinct types of definition used by authors seeking to find a unity for nursing. One type of definition has to do with goals or purposes given to nursing and the other with ends discovered as nursing. But even if there are ends waiting to be discovered a particular practical concern is how we can have knowledge of them. I will suggest that knowledge by intuition is plausible but that as things currently stand in moral epistemology it will not provide the unifying ground for nursing. Then I will argue that in the latter approach to definition a certain account of human nature has been advanced in order to provide features that are there to be discovered and so not dependent on human beings for the definition or classification. However, such an attempt to define nursing cannot do what is wanted. Rather than the account of human nature grounding morality and doing so for nursing, the account of human nature itself relies upon a prior account of morality. Because of this it loses its supposed ground of unity for the profession. Nursing is not united by its moral stance especially if this is understood in a strong sense as unique moral stance, but as things currently stand in moral epistemology this is not necessarily a bad thing for practitioners or patients. © 2012 Blackwell Publishing Ltd.

  8. Unity and diversity in human language.

    Science.gov (United States)

    Fitch, W Tecumseh

    2011-02-12

    Human language is both highly diverse-different languages have different ways of achieving the same functional goals-and easily learnable. Any language allows its users to express virtually any thought they can conceptualize. These traits render human language unique in the biological world. Understanding the biological basis of language is thus both extremely challenging and fundamentally interesting. I review the literature on linguistic diversity and language universals, suggesting that an adequate notion of 'formal universals' provides a promising way to understand the facts of language acquisition, offering order in the face of the diversity of human languages. Formal universals are cross-linguistic generalizations, often of an abstract or implicational nature. They derive from cognitive capacities to perceive and process particular types of structures and biological constraints upon integration of the multiple systems involved in language. Such formal universals can be understood on the model of a general solution to a set of differential equations; each language is one particular solution. An explicit formal conception of human language that embraces both considerable diversity and underlying biological unity is possible, and fully compatible with modern evolutionary theory.

  16. A new unity for angular measurements in strabismus.

    Bicas, Harley E A

    2014-10-01

    The practical advantages of quantifying an angle by a ratio of linear lengths instead of arcs of circles has led to the definition of the prism-diopter, a conventional unity for numbering prisms and measuring strabismic deviations. However, a major inconvenience of using prism-diopter unities to express angular measurements is the non-linearity of the scale, which reaches an infinite value for the angle of 90º, then becomes negative, with decreasing magnitudes for increasing angles between 90º and 180º. As a consequence, arithmetical operations and comparisons of angles measured by such unities present errors of very great magnitudes. In order to retain the advantages of defining an angle by straight line dimensions but to diminish the severe inconveniences of this method, a new definition of the prism-diopter is proposed. Here, instead of defining the prism-diopter by the asymmetrical condition, the conception of this new unity is based on a geometrically symmetrical condition; that of the relationship of an isosceles triangle (where the leg is perpendicular to the bisector of the angle and the bisector itself ). The condition of symmetry for the definition of the new unity represents a conceptual advance because it reproduces the already well accepted, conventional criteria for quantifying the value of a prism, that of its minimum deviation. Furthermore, it corresponds to the most commonly observed clinical conditions of binocular balance. The absolute differences between the unitary values of the prism-diopter and that of the new unity are negligible (0.0025%), but the scale of values expressed by the new unity is closer to the ideal scale of angular measurements. (With the new unity, the infinite value is only reached for an angle of 180º and the errors due to arithmetical operations are much smaller.)

  19. Amyloid precursor protein and endosomal-lysosomal dysfunction in Alzheimer's disease: inseparable partners in a multifactorial disease.

    Nixon, Ralph A

    2017-07-01

    Abnormalities of the endosomal-lysosomal network (ELN) are a signature feature of Alzheimer's disease (AD). These include the earliest known cytopathology that is specific to AD and that affects endosomes and induces the progressive failure of lysosomes, each of which are directly linked by distinct mechanisms to neurodegeneration. The origins of ELN dysfunction and β-amyloidogenesis closely overlap, which reflects their common genetic basis, the established early involvement of endosomes and lysosomes in amyloid precursor protein (APP) processing and clearance, and the pathologic effect of certain APP metabolites on ELN functions. Genes that promote β-amyloidogenesis in AD (APP, PSEN1/2, and APOE4) have primary effects on ELN function. The importance of primary ELN dysfunction to pathogenesis is underscored by the mutations in more than 35 ELN-related genes that, thus far, are known to cause familial neurodegenerative diseases even though different pathogenic proteins may be involved. In this article, I discuss growing evidence that implicates AD gene-driven ELN disruptions as not only the antecedent pathobiology that underlies β-amyloidogenesis but also as the essential partner with APP and its metabolites that drive the development of AD, including tauopathy, synaptic dysfunction, and neurodegeneration. The striking amelioration of diverse deficits in animal AD models by remediating ELN dysfunction further supports a need to integrate APP and ELN relationships, including the role of amyloid-β, into a broader conceptual framework of how AD arises, progresses, and may be effectively therapeutically targeted.-Nixon, R.

    Workers in the Space Station Processing Facility close the access hatch to the Unity connecting module, part of the International Space Station, before its launch aboard Space Shuttle Endeavour on STS-88 in December. Unity will now undergo a series of leak checks before a final purge of clean, dry air inside the module to ready it for initial operations in space. Other testing includes the common berthing mechanism to which other space station elements will dock and the Pad Demonstration Test to verify the compatibility of the module with the Space Shuttle as well as the ability of the astronauts to send and receive commands to Unity from the flight deck of the orbiter. The next time the hatch will be opened it will be by astronauts on orbit. Unity is expected to be ready for installation into the payload canister on Oct. 25, and transported to Launch Pad 39-A on Oct. 27. The Unity will be mated to the Russian-built Zarya control module which should already be in orbit at that time.

  9. Calvin’s view on church discipline and unity: a South African perspective

    Directory of Open Access Journals (Sweden)

    P.J. Strauss

    2010-07-01

    Full Text Available The reformer John Calvin, born in 1509, considers discipline and unity as two essential aspects of the Christian church. According to him, the bond of church discipline is a way to unite church members in the truth of the Word and the Christian faith based thereupon. If discipline is exercised with exaggerated strictness and without compassion, tolerance and love, it can break the unity. Because church unity is essentially a unity of faith, or a unity in the truth of the Word, discipline can sever adulterated elements that threaten the unity from the church. Discipline, if correctly ap- plied, builds the unity of the church as a unity in religious truths.

    Cosmonaut Yuri P. Gidzenko, Expedition One Soyuz commander, stands near the hatch leading from the Unity node into the newly-attached Destiny laboratory aboard the International Space Station (ISS). The Node 1, or Unity, serves as a cornecting passageway to Space Station modules. The U.S.-built Unity module was launched aboard the Orbiter Endeavour (STS-88 mission) on December 4, 1998, and connected to Zarya, the Russian-built Functional Cargo Block (FGB). The U.S. Laboratory (Destiny) module is the centerpiece of the ISS, where science experiments will be performed in the near-zero gravity in space. The Destiny Module was launched aboard the Space Shuttle Orbiter Atlantis (STS-98 mission) on February 7, 2001. The aluminum module is 8.5 meters (28 feet) long and 4.3 meters (14 feet) in diameter. The laboratory consists of three cylindrical sections and two endcones with hatches that will be mated to other station components. A 50.9-centimeter- (20-inch-) diameter window is located on one side of the center module segment. This pressurized module is designed to accommodate pressurized payloads. It has a capacity of 24 rack locations, and payload racks will occupy 13 locations especially designed to support experiments.

  11. US Immigration Policy and the Case for Family Unity

    Directory of Open Access Journals (Sweden)

    Zoya Gubernskaya

    2017-05-01

    Full Text Available As the Trump administration contemplates immigration reform, it is important to better understand what works and what does not in the current system. This paper reviews and critically evaluates the principle of family unity, a hallmark of US immigration policy over the past 50 years and the most important mechanism for immigration to the United States. Since 1965, the United States has been admitting a relatively high proportion of family-based migrants and allowing for the immigration of a broader range of family members. However, restrictive annual quotas have resulted in a long line of prospective immigrants waiting outside of the United States or within the United States, but without status. Further policy changes have led to an increasing number of undocumented migrants and mixed-status families in the United States. Several policies and practices contribute to prolonged periods of family separation by restricting travel and effectively locking in a large number of people either inside or outside of the United States. On top of that, increasingly aggressive enforcement practices undermine family unity of a large number of undocumented and mixed-status families. Deportations — and even a fear of deportation — cause severe psychological distress and often leave US-born children of undocumented parents without economic and social support. A recent comprehensive report concluded that immigration has overall positive impact on the US economy, suggesting that a predominantly family-based migration system carries net economic benefits. Immigrants rely on family networks for employment, housing, transportation, informal financial services, schooling, childcare, and old age care. In the US context where there is nearly no federal support for immigrants’ integration and limited welfare policies, family unity is critical for promoting immigrant integration, social and economic well-being, and intergenerational mobility.

Elaborated explanation in this paper is expected to result in a true understanding of this crucial issue, particularly the concept of religious pluralism in the discourse of Islamic studies. Ibn Arabi’ extensively  discusses religion in the sense of the “ideal” versus “historical” or “esoteric” versus “the exoteric”. Ibn ‘Arabi concludes that the absolute unity of religions may only occur within spiritual, ideal, or transcendental realm (or “esoteric”, which is beyond the formal form of religions. Hence, the transcendental unity of religions cannot be found in the formal form of religions nor in the shari’ah.[Artikel ini mengulas pandangan Ibn ‘Arabi’ mengenai wahdat al-adyan seperti dijelaskan dalam dua bukunya; Futuhat dan Fusus, dan perbedaan dan kesamaan antara iman dan shariah.

Dalam diskusinya, Ibn Arabi’  menjelaskan perbedaan ‘ideal’ dan ‘historikal’ atau antara ‘esoterik’ dan ‘eksoterik’.

    Utilizing Bourdieu's concept of the habitus, Keith Macdonald has recently examined the elite social origins of the British officer corps. His analysis is valid as far at it goes but it ignores the professional practices of British officers. This article examines Britain's Joint Services Command and Staff College to assess the unification of the three services around common forms of military practice. It argues that while the new staff college has been effective in disseminating new forms of professional expertise among British officers, various practices have been institutionalized which actively undermine the unity of the officer corps.

    Full Text Available The author of the paper considers the unity of education as a specific way of existence, blurring the distinction between ontological and anthropological interpretations of education. This approach is supposed to adequately identify the philosophic sense of the category of education without linking it exclusively to the philosophic consideration of educational practice. The author also points out the connection between the ideas of the world unity and of a human being’s education as a process of gradual approaching one’s true and complete image in the history of European philosophy. Even though the contemporary notion of education is most elaborately presented by classical German philosophers, the author aims to show the prospects of addressing the antique philosophic tradition proposing the first conceptualization of education connected with a special ontological position. The author calls attention to the gradual development of views on the systemic nature of being, linking it to the initial didactic guideline of Greek philosophers. The example of Aristotle’s ethics proves the integrity of externally separate ways of making up of a person. The author comes to a conclusion about the necessity of taking the connection of educational concepts and a characteristic tendency to create the philosophic theory of the world, the elements of which are united in an integrated system, into account. In the author’s opinion, it will allow to define the real philosophic and pedagogical sense of the revision of the classical philosophic tradition, undertaken by the contemporary philosophy.

    A method employing a lead-unity-lag adjustment on a power generation system is disclosed. The method may include calculating a unity power factor point and adjusting system parameters to shift a power factor angle to substantially match an operating power angle creating a new unity power factor point. The method may then define operation parameters for a high reactance permanent magnet machine based on the adjusted power level.

    In the Space Station Processing Facility (SSPF), the Unity connecting module, part of the International Space Station, sits on a workstand before its move to a new location in the SSPF. As the primary payload on mission STS-88, scheduled to launch Dec. 3, 1998, Unity will be mated to the Russian-built Zarya control module which should already be in orbit at that time. In the SSPF, Unity is undergoing testing such as the Pad Demonstration Test to verify the compatibility of the module with the Space Shuttle, as well as the ability of the astronauts to send and receive commands to Unity from the flight deck of the orbiter, and the common berthing mechanism to which other space station elements will dock. Unity is expected to be ready for installation into the Shuttle's payload canister on Oct. 25, and transported to Launch Pad 39-A on Oct. 27.

  4. Hmong American Leadership and Unity in the Post-Vang Pao Era

    Directory of Open Access Journals (Sweden)

    Nengher N. Vang

    2015-12-01

    Full Text Available The passing of General Vang Pao (GVP in a hospital in Clovis, California, in 2011 ended an historical era for Hmong Americans and the larger Hmong diaspora. This historical essay explores the changing meanings of leadership and unity for Hmong Americans in the post-GVP era. It first uses sociologist Max Weber's leadership criteria (rational, charismatic, and traditional authority to explain Vang Pao’s enormous influence on the Hmong in Laos and as refugees in the Hmong diaspora. The essay then reviews current sources of rational, charismatic, and traditional leadership in Hmong American communities: electoral politics, non-profit organizations, religion, and clans. The essay concludes that it is unlikely that a large segment of Hmong Americans will ever again coalesce around one leader. Instead, two new political orientations may become more prevalent as the Hmong reconsider their place in the world: one that favors the local over the national, and another which favors transnationalism rather than the quest for their own nation-state

  5. The Paradigm of Unity in Prenatal Education and Pedagogy

    Directory of Open Access Journals (Sweden)

    Kornas-Biela Dorota

    2014-07-01

    Full Text Available The traditional approach to the relation between parents and their prenatal child presents the child as a fetus, a mainly passive recipient of the mother’s vital biological resources. Contemporary prenatal psychology and pedagogy recognizes this relationship in a quite different perspective: the prenatal child is a member of the family and may be seen as an active member of the wider family as a community, extended to grandparents and other relatives. Between parents and their child in the womb exists a reciprocal relationship at a physiological (hormonal, psychological and spiritual level. The prenatal child communicates with the parents in different ways and reacts to their stimulation (acoustic, tactile, loco-motoric, chemo-receptive, thermo-receptive, and emotional. This dialogue of the parents and their prenatal child enriches each member of the family community. In this sense, the prenatal child is a gift and a challenge for the parents to develop their personality, social competences and spiritual life. The reflections presented in this paper fit the conception of the paradigm of unity applied into the area of prenatal education and prenatal pedagogy as a new pedagogical subdisciline.

  6. Unity and universe: understanding pilgrimage to Mount Athos

    Directory of Open Access Journals (Sweden)

    René Gothóni

    2010-01-01

    Full Text Available Having found the specific universal unity of pilgrimages, namely that pilgrimages are journeys of spiritual transformation, the author began to look more closely at the uniqueness of the content of beliefs embodied in pilgrimages to Mount Athos, particularly with the aim of unfolding the universe of beliefs concealed in the word proskýnima, which is the Greek word for ‘pilgrimage’. Therefore, he shifted his focus from the concept to the word ‘pilgrimage’, denoting the human phenomena of visiting holy and sacred places, persons, mountains, wells and so forth. This article illustrates how our preconceptions of the word ‘pilgrimage’ determine our conception of the concept or category of ‘pilgrimage’, which again determines our interpretation and understanding of the content of beliefs of this form of human phenomenon. As a by-product this article also displays the process of how our limited horizon of conceiving the concepts and words is extended in parallel with the process of research. The article shows how this horizon determines our leaving out fundamental elements of ‘pilgrimages’ which, in this case, are characteristic of visits to the Holy Mountain of Greece.

  7. UNITY IN DIVERSITY. THE EUROPEAN UNION’S MULTILINGUALISM

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available It is undeniable that the European Union represents the most ambitious legal and linguistic project, integrating 28 Member States and 24 official languages. What we undertook with this study was to explore the importance of multilingualism in the European Union and the problems that unity in diversity involves. This study tried to touch upon both theoretical aspects (i.e., what the multilingualism of EU law implies and practical issues (i.e., the interaction between legal languages at national and at EU level, problems emerging from multilingualism, illustrated by the relevant case law of the European Court of Justice. In many ECJ cases, it was underlined that multilingualism is essential to the EU legal order. The meaning of EU law cannot be derived from one version of the official languages and the ECJ regularly heads for a uniform interpretation of the contradictory versions. The present study is part of a more complex research on this theme and it is meant to approach certain important points of my PhD thesis. A first part of this research on multilingualism has already been published.

  10. Europeanness: A Path To Unity Within The European Union

    Directory of Open Access Journals (Sweden)

    Piasecki Ryszard

    2016-03-01

    Full Text Available The postwar experience has shown that the implanting of European consciousness, or Europeanness, calls for coordinated efforts among the European institutions, national states, and NGOs. Such consciousness, a key pillar of the European integration, is necessary for the EU to effectively function and motivate member states’ − also the EU’s − citizens. And yet European institutions and EU governments show little interest in promoting the formation of this European consciousness. Pro-European social movements are weak, while anti- European ones gain strength. This désintéressement of the EU countries probably results from the conviction that the goal has been reached and that there is no more need for a widespread pro-European education of their societies. However analysis of the problem, and in particular of the interaction between European and national identities, shows that this is not the case. We fear that this lack of proactive measures mobilizing EU citizens to keep on struggling for a common Europe will lead to the erosion of existing achievements of integration within the EU, and undermine European values. It may threaten the future of the EU, which is not an ordinary integration grouping but a great peaceful, civilizational, social and economic project. Our hypothesis − positively verified in this article − is that the promotion of Europeanness in the EU societies is urgently needed to maintain the unity (and even membership of the Union, and to avert trends unfavorable for all of Europe and therefore for the West as a whole.

  11. Relevance, textual unity, and politeness in writing about science

    Energy Technology Data Exchange (ETDEWEB)

    Kreml, N.M.P.

    1992-01-01

    The question of whether there are social implications of linguistic choices in unifying a text is investigated empirically by this study which accounts for the interpretation of implicatures in conversation and written texts. It considers Relevance Theory (Sperber and Wilson 1988, Blakemore 1987, Blass 1990) to be the explanation of the unity of the text, as opposed to semantic theories of cohesion (Halliday and Hasan 1976) or pragmatic theories of coherence (van Dijk 1977). This study presents a model of three types of textual unifiers: overt (referring specifically to the text), embedded (referring to intra- and extra-textual information), and inference (not referring to the text at all). It hypothesizes that different genres are characterized by the predominance of different types of textual unifiers, and that readers will prefer those texts that rely on inferential unifiers which emphasize the reader's ability to participate in creating the meaning of the text. Eighteen texts of 275 words each are selected from three genres: scientific magazines, introductory science textbooks, and essays on science. The texts are found to vary significantly by genre in the type of textual unifier used. An Overtness Index expresses the ratio of the marked forms: science textbooks have more Overt unifiers (such as connective phrases) and thus a high Overtness Index; essays rely more on Inference unifiers (not represented by words) and thus have a low Overtness Index. The texts are submitted to 188 readers, and a significantly high number of all types of readers prefer the texts with the lower Overtness Indices-the essays. Thus a low Overtness Index is one feature of texts preferred by readers, supporting the hypotheses that genres of texts vary in the type of unifier used and that readers prefer texts that allow them to participate in constructing the meaning of the text.

    2016-03-01

    Full Text Available I attempt to find the main causes of the serious disunity in the Presbyterian Church in Korea (PCK, which started as one church but is now divided into more than 100 denominations, as well as a solution to promote the unity of the PCK. This attempt starts with an exegesis of Ephesians, with special reference to Ephesians 4:1�16, to understand the biblical principle on this matter. This article draws on a mature ecclesiology and a mature sense of unity as key concepts. After that, the history of the PCK disunity is briefly described, dealing with four major schisms. Based on this historical investigation, the disunity in the PCK is assessed. In addition, the weak sense of unity and weak ecclesiology of the PCK, which played a role in its disunity, are discussed in view of the confessions of faith, the ministry of the word and the Lord�s Supper, and ecumenical efforts in relation to national and international ecumenical organisations. Lastly, contributory suggestions based on the mature sense of unity are offered to the PCK in particular and the Reformed family and all Christian churches in general.Intradisciplinary and/or interdisciplinary implications: In my ecumenical Reformed intradisciplinary assessment of unity and catholicity in the PCK, which started as one church but is now divided into more than 100 denominations, I identify the main causes of serious disunity in the PCK, namely a weak sense of unity, immaturity and secularisation.

  17. The diversity and unity of reactor noise theory

    International Nuclear Information System (INIS)

    Kuang, Zhifeng

    2001-01-01

    The study of reactor noise theory concerns questions about cause and effect relationships, and the utilisation of random noise in nuclear reactor systems. The diversity of reactor noise theory arises from the variety of noise sources, the various mathematical treatments applied and the various practical purposes. The neutron noise in zero-energy systems arises from the fluctuations in the number of neutrons per fission, the time between nuclear events, and the type of reactions. It can be used to evaluate system parameters. The mathematical treatment is based on the master equation of stochastic branching processes. The noise in power reactor systems is given rise by random processes of technological origin such as vibration of mechanical parts, boiling of the coolant, fluctuations of temperature and pressure. It can be used to monitor the reactor behaviour with the possibility of detecting malfunctions at an early stage. The mathematical treatment is based on the Langevin equation. The unity of reactor noise theory arises from the fact that the useful information from noise is embedded in the second moments of random variables, which lends the possibility of building up a unified mathematical description and analysis of the various reactor noise sources. Exploring such possibilities is the main subject among the three major topics reported in this thesis. The first subject is within the zero power noise in steady media, and we reported on the extension of the existing theory to more general cases. In Paper I, by use of the master equation approach, we have derived the most general Feynman- and Rossi-alpha formulae so far by taking the full joint statistics of the prompt and all the six groups of delayed neutron precursors, and a multiple emission source into account. The involved problems are solved with a combination of effective analytical techniques and symbolic algebra codes. Paper II gives a numerical evaluation of these formulae. An assessment of the

    2017-12-01

    Using the cross-platform game engine Unity, we develop virtual laboratories for PC, consoles, mobile devices and website as an innovative tool to study physics. There is extensive uptake of ICT in the teaching of science and its impact on the learning, and considering the limited availability of laboratories for physics teaching and the difficulties this causes in the learning of school students, we design the virtual laboratories to enhance studentâĂŹs knowledge of concepts in physics. To achieve this goal, we use Unity due to provide support bump mapping, reflection mapping, parallax mapping, dynamics shadows using shadows maps, full-screen post-processing effects and render-to-texture. Unity can use the best variant for the current video hardware and, if none are compatible, to use an alternative shader that may sacrifice features for performance. The control over delivery to mobile devices, web browsers, consoles and desktops is the main reason Unity is the best option among the same kind cross-platform. Supported platforms include Android, Apple TV, Linux, iOS, Nintendo 3DS line, macOS, PlayStation 4, Windows Phone 8, Wii but also an asset server and Nvidia’s PhysX physics engine which is the most relevant tool on Unity for our PhysLab.

  19. Does John 17:11b, 21−23 refer to church unity?

    Directory of Open Access Journals (Sweden)

    Gert J. Malan

    2011-04-01

    Full Text Available In ecumenical circles, John 17:11b, 21–23 has been understood as Jesus’ prayer for church unity, be it confessional or structural. This article questioned such readings and conclusions from historical, literary and sosio-cultural viewpoints. The Fourth Gospel’s language is identified as ’antilanguage’ typical of an ’antisociety’, like that of the Hermetic, Mandean and Qumran sects. Such a society is a separate entity within society at large, but opposes it. Read as a text of an antisociety, John 17:11b, 21–23 legitimises the unity of the separatist Johannine community, which could have comprised several such communities. This community opposed the Judean religion, Gnosticism, the followers of John the Baptist and three major groups in early Christianity. As text from the canon, this Johannine text legitimates tolerance of diversity rather than the confessional or structural unity of the church.

    Feeling that you belong in a group is an important and powerful need. The ability to foster a sense of belonging can also determine whether groups survive. Organizational features of groups cultivate feelings of belonging, yet prior research fails to investigate the idea that belief systems also play a major role. Using multilevel data, this study finds that church members' traditional beliefs, group-level belief unity, and their interaction associate positively with members' sense of belonging. In fact, belief unity can be thought of as a “sacred canopy” under which the relationship between traditional beliefs and feelings of belonging thrives.

    Full Text Available Tawhid (the belief in transcendent oneness or unity of divinity is the culmination of all Islamic teachings and has a special place in Islamic sciences. The unity of essence begins by the unity of existential necessity and ends in unity of existence as many theosophers and mystics suggest. This essay discusses unity of essence as understood by two Sadraean thinkers (Hakim Mudarres Zunuzi and Banu Amin according to Mulla Sadra's principles. Undoubtedly, these two theosophers have no discord as far as they speak about necessity of existence and unity of Necessary Existence. Dispute erupts when Banu voices her Sadraean sympathy with transcendent oneness of existence while Mudarres takes another position.       According to Sadra, the being which has no limitation whatsoever leaves no room for other being to come into existence and be its second or third and thus it is unique and uncountable. In this world, thus, there is no existence but one of which the rest are manifestations (Mulla Sadra, 1382, 67. This view which has been mentioned by Sadra in different positions is the very idea of individual unity of existence. It needs to be explained that in Mulla Sadra's works there are two accounts of effect: Existence in itself for something-else (relational existence Existence for something-else (copulative existence      At first sight which is thought to be elementary as compared to the second one, effect enjoys a reality and existence of its own the whole identity of which is though being related to and depended on cause and this dependency is its very essence and undetachable but the effect like the cause is counted among  beings. This is the position which is also held by Mudarres Zunuzi as to contingent beings (Mudarres Zunuzi, 1376: 357. He seem to have understood Mulla Sadra's words implying this very sense alone without presuming the possibility of a second sense. To put it otherwise, he has indeed fathomed effect's copulative

  2. Cultural pluralism and the future of American unity: the impact of illegal aliens.

    Science.gov (United States)

    1984-01-01

    This paper explores the question of the impact of illegal migration on American unity and cultural pluralism in the US. Assuming that over time the descendants of undocumented workers now in the US will behave substantially like descendants of those who immigrate legally, the long-term impact of illegal migration barely will be noticeable provided it is reduced substantially in the future. The process of acculturation will work in the same way for both groups as it has for other ethnic groups in the past, given comparable levels of education and length of family residence in the US. The author takes special notice of the illegal migration of Spanish-speaking workers and hypothesizes that the behavior of their descendants will not differ from that of the descendants of other immigrants, legal or illegal, in ways that disrupt fundamental patterns of American political unity and cultural pluralism.

    A family of organically templated aluminophosphates (denoted AlPOs) with an Al/P ratio of non-unity has been prepared with 1-D chain, 2-D layer and 3-D open-framework architectures. Their inorganic parts are constructed from alternating Al-centered polyhedra (AlO 4, AlO 5, AlO 4(OH 2) 2) and P-centered tetrahedra P(OAl) nO 4- n ( n=0, 1, 2, 3). The existence of terminal POH and/or PO groups in the structures results in the deviation of Al/P ratio from unity, and the commonly encountered Al/P ratios are 1/2, 3/5, 2/3, 3/4, 4/5 and 5/6. This review will discuss the structural features of these AlPOs with various dimensionalities and stoichiometries.

    2015-12-01

    The essence of physical reality-what the world consists of-has been a heated focus of contention for millennia. First with philosophers and then with physicists, the debate has been polarized since the beginning: while those loosely known as Platonists search for an underlying unity in nature, others caution that such unity is unachievable in practice and in principle. In this essay, we review both positions, arguing strongly for the latter in anticipation of experimental results from the Large Hadron Collider, the particle accelerator from the European Center for Nuclear Research. We further argue that, for the first time in history, the material essence of reality could be determined from an empirical standpoint as opposed to a purely dialectic one, settling the age-old debate. © 2015 New York Academy of Sciences.

  9. Body-self unity and self-esteem in patients with rheumatic diseases.

    Science.gov (United States)

    Bode, Christina; van der Heij, Anouk; Taal, Erik; van de Laar, Mart A F J

    2010-12-01

    Perceptions and evaluations of the own body are important sources of self-esteem. Having a rheumatic disease challenges maintenance of positive self-esteem due to consequences of the disease such as unfavorable sensations as pain and limited (physical) functioning. We expect that a positive experience of the own body in spite of a rheumatic disease (body-self harmony) will be associated with higher levels of self-esteem and that experiencing the body as unworthy part of the own person or as disabler for own strivings (body-self alienation) will result in lower levels of self-esteem. For this explorative study, the body experience questionnaire (BEQ) measuring body-self unity was developed and piloted. One hundred sixty-eight patients visiting the outpatient rheumatology clinic of the Medisch Spectrum Twente, Enschede, The Netherlands, completed a questionnaire on touchscreen computers to measure body-self unity (BEQ), illness cognitions (illness cognition questionnaire), pain intensity, functional limitations (health assessment questionnaire disability index), self-esteem (Rosenberg Self-Esteem Scale) and demographics. To analyze predictors of self-esteem, hierarchical regression analyses were employed. The BEQ revealed a two-factor structure with good reliability (subscale harmony, four items, Cronbach's α = 0.76; subscale alienation, six items, Cronbach's α = 0.84). The final model of the hierarchical regression analyses showed that self-esteem can be predicted by the illness cognitions helplessness and acceptance, by harmony and most strongly by alienation from the body. R(2) of the final model was 0.50. The relationship between functional limitations and self-esteem was totally mediated by the psychological constructs body-self unity and illness cognitions. This explorative study showed the importance of the unity of body and self for self-esteem in patients with a rheumatic disease.

  11. Quantum groups, roots of unity and particles on quantized Anti-de Sitter space

    Energy Technology Data Exchange (ETDEWEB)

    Steinacker, Harold [Univ. of California, Berkeley, CA (United States). Dept. of Physics

    1997-05-23

    Quantum groups in general and the quantum Anti-de Sitter group Uq(so(2,3)) in particular are studied from the point of view of quantum field theory. The author shows that if q is a suitable root of unity, there exist finite-dimensional, unitary representations corresponding to essentially all the classical one-particle representations with (half) integer spin, with the same structure at low energies as in the classical case. In the massless case for spin ≥ 1, "naive" representations are unitarizable only after factoring out a subspace of "pure gauges", as classically. Unitary many-particle representations are defined, with the correct classical limit. Furthermore, the author identifies a remarkable element Q in the center of Uq(g), which plays the role of a BRST operator in the case of Uq(so(2,3)) at roots of unity, for any spin ≥ 1. The associated ghosts are an intrinsic part of the indecomposable representations. The author shows how to define an involution on algebras of creation and anihilation operators at roots of unity, in an example corresponding to non-identical particles. It is shown how nonabelian gauge fields appear naturally in this framework, without having to define connections on fiber bundles. Integration on Quantum Euclidean space and sphere and on Anti-de Sitter space is studied as well. The author gives a conjecture how Q can be used in general to analyze the structure of indecomposable representations, and to define a new, completely reducible associative (tensor) product of representations at roots of unity, which generalizes the standard "truncated" tensor product as well as many-particle representations.

  17. Stress Intensity Factor Extraction from the Enriched Partition of Unity Solution for a Cracked Linear Elastic Medium

    Energy Technology Data Exchange (ETDEWEB)

    2017-02-15

    The stress intensity factor is a useful tool for predicting material failure and describing the stress states of brittle materials. We present a technique to calculate the stress intensity factor for a linear elasticity problem on a cracked domain with an enriched partition of unity method. We use a particular partition of unity function, which is piecewise polynomial and has wide flat-top region. The flat-top area in the partition of unity function helps the displacements and the stress fields in the vicinity of the crack tip to be accurately represented, even with a coarse background mesh. Among other methods for calculating the stress intensity factor, we find that the direct extraction method is the most accurate and efficient one given a relatively coarse background mesh for the enriched partition of unity method.

    Full Text Available Current theorizing on genre within Systemic Functional Linguiscs (SFL as well as other traditions of genre analysis have not paid much attention to the interrelationship between the notions of rhetorical mode and genre. In this paper I argue that rhetorical mode may be an important notion in genre studies and that it should thus be foregrounded. I elaborate on the different linguistic and functional status of genres and rhetorical modes attempting to show that it is essential for text/discourse analysis to draw a clear distinction between them. Within this perspective I propose that while genres stand for diversity and fit the notion of specific text type identifiable by specific format and used in specific social contexts to fulfil specific functions, rhetorical modes stand for unity as they constitute general patterns of language organisation strategically used by authors/ writers as linguistic resources in the creation of specific genres. I illustrate the discussion by analysing the strategic use of clause relations as rhetorical modes occurring in a specific genre, namely, a fable.

    Kuang, Ping; Deinega, Alexei; Hsieh, Mei-Li; John, Sajeev; Lin, Shawn-Yu

    2013-10-15

    We report what is to our knowledge the first observation of the effect of parallel-to-interface-refraction (PIR) in a three-dimensional, simple-cubic photonic-crystal. PIR is an acutely negative refraction of light inside a photonic-crystal, leading to light-bending by nearly 90 deg over broad wavelengths (λ). The consequence is a longer path length of light in the medium and an improved light absorption beyond the Lambertian limit. As an illustration of the effect, we show near-unity total absorption (≥98%) in λ=520-620 nm and an average absorption of ~94% over λ=400-700 nm for our α-Si:H photonic-crystal sample of an equivalent bulk thickness of t˜=450 nm. Furthermore, we have achieved an ultra-wide angular acceptance of light over θ=0°-80°. This demonstration opens up a new door for light trapping and near-unity solar absorption over broad λs and wide angles.

  8. Unity and Diversity of Executive Functions: Individual Differences as a Window on Cognitive Structure

    Science.gov (United States)

    Friedman, Naomi P.; Miyake, Akira

    2016-01-01

    Executive functions (EFs) are high-level cognitive processes, often associated with the frontal lobes, that control lower level processes in the service of goal-directed behavior. They include abilities such as response inhibition, interference control, working memory updating, and set shifting. EFs show a general pattern of shared but distinct functions, a pattern described as “unity and diversity.” We review studies of EF unity and diversity at the behavioral and genetic levels, focusing on studies of normal individual differences and what they reveal about the functional organization of these cognitive abilities. In particular, we review evidence that across multiple ages and populations, commonly studied EFs (a) are robustly correlated but separable when measured with latent variables; (b) are not the same as general intelligence or g; (c) are highly heritable at the latent level and seemingly also highly polygenic; and (d) activate both common and specific neural areas and can be linked to individual differences in neural activation, volume, and connectivity. We highlight how considering individual differences at the behavioral and neural levels can add considerable insight to the investigation of the functional organization of the brain, and conclude with some key points about individual differences to consider when interpreting neuropsychological patterns of dissociation.

    Solar energy modelling is increasingly popular, important, and economic significant in solving energy crisis for big cities. It is a clean and renewable resource of energy that can be utilized to accommodate individual or group of buildings electrical power as well as for indoor heating. Implementing photovoltaic system (PV) in urban areas is one of the best options to solve power crisis over expansion of urban and the growth of population. However, as the spaces for solar panel installation in cities are getting limited nowadays, the available strategic options are only at the rooftop and façade of the building. Thus, accurate information and selecting building with the highest potential solar energy amount collected is essential in energy planning, environmental conservation, and sustainable development of the city. Estimating the solar energy/radiation from rooftop and facade are indeed having a limitation - the shadows from other neighbouring buildings. The implementation of this solar estimation project for Istanbul uses CityGML LoD2-LoD3. The model and analyses were carried out using Unity 3D Game engine with development of several customized tools and functionalities. The results show the estimation of potential solar energy received for the whole area per day, week, month and year thus decision for installing the solar panel could be made. We strongly believe the Unity game engine platform could be utilized for near future 3D mapping visualization purposes.

    A model for monitoring catalyst mass flow in riser of Fluid Catalytic Cracking - FCC, pilot unity as a function of air flow and solid injection is proposed. The fluidized FCC- catalyst bed system is investigated in an experimental setup the Cold Pilot Unity - CPU by means of gamma ray transmission measurements. Riser in CPU simulates the reactor in FCC process. By automation control air flow is instrumentally measured in riser and the solid injection is manually controlled by valve adjusting. Keeping a constant solid injection, catalyst level at the return column was measured by gamma transmission for several air flow values in riser. The operational condition reached a steady state regime before given to setup a new air flow value. A calibration of catalyst level as a function of air flow in riser is calculated, therefore, a model for solid feed rate is derived. Recent published work evaluates solid concentration in riser of the CPU by means of gamma ray transmission, and a correlation with air velocity is obtained. In this work, the model for solid feed rate was further investigated by carrying out experiments to measure catalyst concentration at the same air flow values. These experiments lead to a model for monitoring catalyst flow in riser as function of solid feed rate and air flow. Simulation with random numbers produced with Matlab software allows to define validation criteria for the model parameters. (author)

    Full Text Available Education has a vital role in smartening up human life; it is not surprising that the way to measure the quality of a civilization is determined by the quality of its educators. In the modern and heterogenic era as today, education with multicultural insight is required in order to give understanding about the importance of unity and diversity, so it is expected that there will be no more violence in the name of race, ethnicity, culture and even religion. Islam is often perceived as a harsh, exclusive and sectarian religion, whereas Islam is full of moral values, compassion, tolerance and inclusion. In response, Islamic education is required to give an understanding to the world that Islam is a religion that respects multiculturalism. This is where Islamic education with multicultural insight must be present in order to explain the relationship between man and God (hablun min Allah, theological aspects; the relationship of unity, namely human relationships with others (hablun min al-nas, anthropo-sociological aspects; and human relationship with the natural surroundings (hablun mi al-’Alam, cosmological aspect.

    Full Text Available The meaning of the concept of society’s organic unity has been investigated. This concept was an important part of Russian religious philosophy in the middle of the XIX century. It has been found that Schelling and Hegel idealistic philosophy and orthodox theology were the main sources of the concept of organic unity. The character and forms of the presentation of the organic unity’s concept in Vladimir Soloviev and the main representatives of early Slavophilism’s social philosophy and philosophy of history has been analyzed. By Solovyov, the subject of the historical development is mankind as holistic, organic phenomenon which tries to overcome the formal unity and to reach its spiritual level in the form of «God-manhood». Economic and legal unity is called the lowest form of unity by Solovyov, and the highest one, which reaches the organic and conscious level, is the spiritual unity. In the philosophy of Ivan Kireyevski, society’s organic unity is opposed to the formal, rational unity. The formal unity was inherited by Europe from ancient Rome. Cultural traditions of Greece and Orthodoxy were inherited by Slavs and saved the spiritual unity of society. According to Alexey Khomyakov, there are two contrasting models of culture: Iranian and Cushitic ones. Iranian model is based on freedom and conscious action. Iranian model creates a spiritual unity without suppression of individuals in society. Cushitic model creates a formal unity, it coercions and suppress individuals. The formality of the state association and the spiritual unity of the community have been opposed by Konstantin Aksakov. In tsarist Russia, all power was given to the monarch to protect the community. Therefore, Russia maintained an organic, internal unity of the people unlike Europe. In Europe, the state became stronger then the communities and state there suppressed communities. Rights and economy became to be more important than morality. European society became

    A recent proof of Bell's theorem without inequalities [A. Cabello, Phys.Rev.Lett. 86, 1911 (2001)] is formulated as a Greenberger-Horne-Zeilinger--type proof involving just two observers. On one hand, this new approach allows us to derive an experimentally testable Bell inequality which is violated by quantum mechanics. On the other hand, it leads to a new state-independent proof of the Kochen-Specker theorem and provides a wider perspective on the relations between the major proofs of no hidden variables

    Full Text Available For generic values of q, all the eigenvectors of the transfer matrix of the Uqsl(2-invariant open spin-1/2 XXZ chain with finite length N can be constructed using the algebraic Bethe ansatz (ABA formalism of Sklyanin. However, when q is a root of unity (q=eiπ/p with integer p≥2, the Bethe equations acquire continuous solutions, and the transfer matrix develops Jordan cells. Hence, there appear eigenvectors of two new types: eigenvectors corresponding to continuous solutions (exact complete p-strings, and generalized eigenvectors. We propose general ABA constructions for these two new types of eigenvectors. We present many explicit examples, and we construct complete sets of (generalized eigenvectors for various values of p and N.

    2016-12-01

    Full Text Available This text explores some of the great challenges present in the cultural landscape of today, such as globalization and its associated phenomena – (internationalisation and ultra-contemporaneousness; exasperated economism with its outcome in the scrap culture; the “piecemeal third world war”, according to Pope Francis’ effective expression, which is connected with a widespread and still poorly understood post-humanism and transhumanism; nihilism and the eclipse of religion as an institution. It considers the light that might be shed by the culture arising from the Focolare’s charism of unity, in order to address these challenges rigorously and without hasty demonizing. The overall picture is not intended to be negative but, without being naive, to offer an interpretation that is able to discern the work of the Spirit in the dramatic scenario of present times.

    2017-10-01

    In order to achieve the enhancement and manipulation of light absorption in graphene monolayer within the visible (Vis) and near infrared (NIR) regions, a design of absorber inspired by contact coupled gratings with an absentee layer is demonstrated. It is proved that the absorptance of monolayer graphene can be greatly enhanced to near unity through rigorous coupled-wave analysis (RCWA) numerical calculation. The thickness of grating and homogeneous absentee layers can significantly change the linewidth and resonant mode position in absorption spectrum. Furthermore, the lateral shift of the contact coupled gratings changes the magnetic field distributions in the grating cavity and the surface-confined mode at the cover/grating interface, thus facilitating the dynamic control of the spectral bandwidth of the graphene absorber. The proposed devices could be efficiently exploited as tunable and selective absorbers, allowing to realize other two-dimensional (2D) materials-based selective photo-detectors.

    In 1971 Lord (Victor) Rothschild published his report for the government, The organisation and management of government R&D, and Sir Peter Medawar launched a campaign for the election of Sir Karl Popper to Fellowship of the Royal Society. We explore these two developments in the contexts of the then current views of the role and purpose of science, and their underpinning philosophy. Although the political battle was won by Rothschild, resulting in major changes to the funding and management of applied R&D, we argue that, despite this, Medawar's campaign for Popper provided an embattled science community with a philosophical basis for defending pure research and the unity of basic and applied science.

    Zames (1981) has observed that there is, in general, no 'separation principle' to guarantee optimality of a division between control law design and filtering of plant uncertainty. Peczkowski and Sain (1978) have solved a model matching problem using transfer functions. Taking into consideration this investigation, Peczkowski et al. (1979) proposed the Total Synthesis Problem (TSP), wherein both the command/output-response and command/control-response are to be synthesized, subject to the plant constraint. The TSP concept can be subdivided into a Nominal Design Problem (NDP), which is not dependent upon specific controller structures, and a Feedback Synthesis Problem (FSP), which is. Gejji (1980) found that NDP was characterized in terms of the plant structural matrices and a single, 'good' transfer function matrix. Sain et al. (1981) have extended this NDP work. The present investigation is concerned with a study of FSP for the unity feedback case. NDP, together with feedback synthesis, is understood as a Total Synthesis Problem.

    Full Text Available The article examines the phenomenon of corporatism, which under the adverse external environment can be used by the professional community to improve the effectiveness of organization. The authors define corporatism of the professional society as a combination of homogenous interests, attitudes, traditions and values; and provide a sociological interpretation of the corporate unity through its organizational and behavioral parameters. The former consists of the perception of the organization reliability, the staff’s confidence in the future, satisfaction with the financial situation (static features, estimates of the innovative capabilities of the company, and the willingness to develop (dynamic features. The behavioral parameters include staff’s values and patterns of behavior that can contribute to the consolidation of the professional community. The authors believe that for corporate management vertical social ties are less important that the horizontal ones, such as the rule of law and honesty, and the team unity under the unstable external environment. The sample of the study conducted by the authors in 2015 consisted of various types of settlements typical for the Sverdlovsk Region: mono-towns and mono-settlements (Nizhny Tagil, Serov, towns and villages with the differentiated economic activities (Ekaterinburg, Irbit. The results of the empirical study of corporatism among different professional societies - industrial workers, social services’ and business organizations’ staff, individual entrepreneurs and authorities - revealed the internal resources that can reduce tensions on the labor market. The research data can be useful for the comparative analysis of corporatism in different regions of Russia (not only industrial and similar to the Ural Region, but differing from it by significant social and economic parameters.

    2017-08-01

    The "Unity of Knowing and Doing" (UKD) theory is proposed by an ancient Chinese philosopher, Wang Shouren, in 1508, which explains how to unify knowledge and practice. Different from the Chinese traditional UKD theory, the international higher education usually treats knowledge and practice as independent, and puts more emphasis on knowledge. Oriented from the UKD theory, the College of Opto-electric Science and Engineering (COESE) at National University of Defense Technology (NUDT) explores a novel training model in cultivating opto-electric professionals from the aspects of classroom teaching, practice experiment, system experiment, design experiment, research experiment and innovation experiment (CPSDRI). This model aims at promoting the unity of knowledge and practice, takes how to improve the students' capability as the main concern and tries to enhance the progress from cognition to professional action competence. It contains two hierarchies: cognition (CPS) and action competence (DRI). In the cognition hierarchy, students will focus on learning and mastering the professional knowledge of optics, opto-electric technology, laser, computer, electronics and machine through classroom teaching, practice experiment and system experiment (CPS). Great attention will be paid to case teaching, which links knowledge with practice. In the action competence hierarchy, emphasis will be placed on promoting students' capability of using knowledge to solve practical problems through design experiment, research experiment and innovation experiment (DRI). In this model, knowledge is divided into different modules and capability is cultivated on different levels. It combines classroom teaching and experimental teaching in a synergetic way and unifies cognition and practice, which is a valuable reference to the opto-electric undergraduate professionals' cultivation.

  7. Sustainability Science as a Transdisciplinary Framework for Institutional Transformation at Unity College

    Science.gov (United States)

    Mulkey, S. S.

    2012-12-01

    Interdisciplinary programming in higher education is accepted as necessary for effective instructional delivery of complex environmental problems. Difficulties in sharing resources among disciplinary units and the need for students to sequentially access information from different disciplines limit the effectiveness of this approach. In contrast, transdisciplinary programming requires that the perspectives of various disciplines be simultaneously integrated in problem-focused pedagogy. Unity College, an environmental college in Maine, has recently adopted Sustainability Science (sensu U.S. National Academy of Science) as a framework for transdisciplinary pedagogy throughout all of its degree programs. Sustainability Science is a promising alternative framework that focuses on the dynamics of coupled human-natural systems and is defined by the problems that it addresses rather than by the disciplines it employs. Students are empowered to become brokers of knowledge, while faculty perform a curatorial role to provide students with networked resources generally external to the classroom. Although the transdisciplinary framework is effective for delivery of Sustainability Science in upper division and capstone courses, we propose this approach also for elements of our general education curriculum during the first two years of our baccalaureate programs. Classroom time is liberated for experiential student engagement and recitation. Our experience suggests that transdisciplinary programming can provide students with critical thinking skills and thus enhance the postgraduate value of their baccalaureate degree. We are coordinating the development of this distinctive curriculum delivery with a marketing program that will make Unity College accessible to a wider range of clientele. Our implementation of transdisciplinary programming will occur over a four-year period and requires explicit and fundamental change in essentially all aspects of College administration and

  17. Effects of non-unity Lewis number of gas-phase species in turbulent nonpremixed sooting flames

    KAUST Repository

    Attili, Antonio

    2016-02-13

    Turbulence statistics from two three-dimensional direct numerical simulations of planar n-heptane/air turbulent jets are compared to assess the effect of the gas-phase species diffusion model on flame dynamics and soot formation. The Reynolds number based on the initial jet width and velocity is around 15, 000, corresponding to a Taylor scale Reynolds number in the range 100 ≤ Reλ ≤ 150. In one simulation, multicomponent transport based on a mixture-averaged approach is employed, while in the other the gas-phase species Lewis numbers are set equal to unity. The statistics of temperature and major species obtained with the mixture-averaged formulation are very similar to those in the unity Lewis number case. In both cases, the statistics of temperature are captured with remarkable accuracy by a laminar flamelet model with unity Lewis numbers. On the contrary, a flamelet with a mixture-averaged diffusion model, which corresponds to the model used in the multi-component diffusion three-dimensional DNS, produces significant differences with respect to the DNS results. The total mass of soot precursors decreases by 20-30% with the unity Lewis number approximation, and their distribution is more homogeneous in space and time. Due to the non-linearity of the soot growth rate with respect to the precursors\\' concentration, the soot mass yield decreases by a factor of two. Being strongly affected by coagulation, soot number density is not altered significantly if the unity Lewis number model is used rather than the mixture-averaged diffusion. The dominant role of turbulent transport over differential diffusion effects is expected to become more pronounced for higher Reynolds numbers. © 2016 The Combustion Institute.

  18. Application of the Unity Rockfall Model to Variable Surface Material Conditions

    Sala, Zac; Hutchinson, D. Jean; Ondercin, Matthew

    2017-04-01

    Rockfall is a geological process that poses risks to the safe operation of transportation infrastructure in mountainous environments world wide. The Unity rockfall model was created as a tool for 3D rockfall simulation as part of the Railway Ground Hazards Research Program, studying the impact of geotechnical hazards affecting Canadian railways [1]. The Unity rockfall model demonstrates the applicability of 3D video game engines for the development of realistic simulations, leveraging high-resolution site data collected using remote sensing techniques. Currently work is being done to further calibrate the model as an engineering tool for decision support. Calibration datasets include high-resolution terrestrial LiDAR and helicopter photogrammetry data collected as part of an ongoing rockfall monitoring program along the Thompson River Valley in south-central British Columbia, Canada. Change detection techniques developed as part of the program have been used to construct a database of rockfall event history and to develop magnitude-frequency relationships for rockfalls in the area [2][3]. Data collected as part of a controlled rock-rolling field program in Christchurch, New Zealand [4] is also being utilized for model calibration. Data on block dynamics for the artificially triggered rockfalls were collected through the use of embedded motion sensors and a sixteen camera setup. These experiments provide detailed information on block kinematics, and capture each impact point of the rockfall with the slope, thus offering a valuable dataset for comparison with modelling results. The research reported here explores the ability of the game engine based modelling technique to simulate rockfall under the variable slope conditions present at each of the sites where calibration data was collected. This includes steep natural rock slopes, with debris-talus cover, as well as shallower slopes with soil cover and vegetation. The varying slope conditions in each environment

    Power Supplies (PSs) employed in personal computers pollute the single phase ac mains by drawing distorted current at a substandard Power Factor (PF). The harmonic distortion of the supply current in these personal computers are observed 75% to 90% with the Crest Factor (CF) being very high which escalates losses in the distribution system. To find a tangible solution to these issues, a non-isolated PFC converter is employed at the input of isolated converter that is capable of improving the input power quality apart from regulating the dc voltage at its output. This is given to the isolated stage that yields completely isolated and stiffly regulated multiple output voltages which is the prime requirement of computer PS. The operation of the proposed PS is evaluated under various operating conditions and the results show improved performance depicting nearly unity PF and low input current harmonics. The prototype of this PS is developed in laboratory environment and test results are recorded which corroborate the power quality improvement observed in simulation results under various operating conditions.

    Broadband unity absorption in graphene-insulator-metal (GIM) structures is demonstrated in the visible (VIS) and near-infrared (NIR) spectra. The spectral characteristics possess broadband absorption peaks, by simply choosing a stack of GIM, while no nanofabrication steps and patterning are required, and thus can be easily fabricated to cover a large area. The electromagnetic (EM) waves can be entirely trapped and the absorption can be greatly enhanced are verified with the finite-difference time-domain (FDTD) and rigorous coupled wave analysis (RCWA) methods. The position and the number of the absorption peak can be totally controlled by adjusting the thickness of the insulator layer. The proposed absorber maintains high absorption (above 90%) for both transverse electric (TE) and transverse magnetic (TM) polarizations, and for angles of incidence up to 80°. This work opens up a promising approach to realize perfect absorption (PA) with ultra-thin film, which could implicate many potential applications in optical detection and optoelectronic devices.

    2017-09-01

    Simulations have become increasingly important for science and there is an increasing emphasis on the visualization of simulations within a Virtual Reality (VR) environment. Our group is exploring this capability as a visualization tool not just for those curious about science, but also for educational purposes for K-12 students. Using data collected in 3-D by a Time Projection Chamber (TPC), we are able to visualize nuclear and cosmic events. The Unity game engine was used to recreate the TPC to visualize these events and construct a VR application. The methods used to create these simulations will be presented along with an example of a simulation. I will also present on the development and testing of this program, which I carried out this past summer at MSU as part of an REU program. We used data from the S πRIT TPC, but the software can be applied to other 3-D detectors. This work is supported by the U.S. Department of Energy under Grant Nos. DE-SC0014530, DE-NA0002923 and US NSF under Grant No. PHY-1565546.

    3D City modelling is increasingly popular and becoming valuable tools in managing big cities. Urban and energy planning, landscape, noise-sewage modelling, underground mapping and navigation are among the applications/fields which really depend on 3D modelling for their effectiveness operations. Several research areas and implementation projects had been carried out to provide the most reliable 3D data format for sharing and functionalities as well as visualization platform and analysis. For instance, BIMTAS company has recently completed a project to estimate potential solar energy on 3D buildings for the whole Istanbul and now focussing on 3D utility underground mapping for a pilot case study. The research and implementation standard on 3D City Model domain (3D data sharing and visualization schema) is based on CityGML schema version 2.0. However, there are some limitations and issues in implementation phase for large dataset. Most of the limitations were due to the visualization, database integration and analysis platform (Unity3D game engine) as highlighted in this paper.

    In the first chapters the author describes how our knowledge of the position of Earth in space and time has developed, thanks to the work of many generations of astronomers and physicists. He discusses how our position in the Galaxy was discovered, and how in 1929, Hubble uncovered the fact that the Universe is expanding, leading to the picture of the Big Bang. He then explains how astronomers have found that the laws of physics that were discovered here on Earth and in the Solar System (the laws of mechanics, gravity, atomic physics, electromagnetism, etc.) are valid throughout the Universe. This is illustrated by the fact that all matter in the Universe consists of atoms of the same chemical elements that we know on Earth. This unity is all the more surprising when one realizes that in the original Big Bang theory, different parts of the Universe could never have communicated with each other. It then is a mystery how they could have shared the same physical laws. This problem was solved by the introduction ...

  8. Moral psychology is relationship regulation: moral motives for unity, hierarchy, equality, and proportionality.

    Science.gov (United States)

    Rai, Tage Shakti; Fiske, Alan Page

    2011-01-01

    Genuine moral disagreement exists and is widespread. To understand such disagreement, we must examine the basic kinds of social relationships people construct across cultures and the distinct moral obligations and prohibitions these relationships entail. We extend relational models theory (Fiske, 1991) to identify 4 fundamental and distinct moral motives. Unity is the motive to care for and support the integrity of in-groups by avoiding or eliminating threats of contamination and providing aid and protection based on need or empathic compassion. Hierarchy is the motive to respect rank in social groups where superiors are entitled to deference and respect but must also lead, guide, direct, and protect subordinates. Equality is the motive for balanced, in-kind reciprocity, equal treatment, equal say, and equal opportunity. Proportionality is the motive for rewards and punishments to be proportionate to merit, benefits to be calibrated to contributions, and judgments to be based on a utilitarian calculus of costs and benefits. The 4 moral motives are universal, but cultures, ideologies, and individuals differ in where they activate these motives and how they implement them. Unlike existing theories (Haidt, 2007; Hauser, 2006; Turiel, 1983), relationship regulation theory predicts that any action, including violence, unequal treatment, and "impure" acts, may be perceived as morally correct depending on the moral motive employed and how the relevant social relationship is construed. This approach facilitates clearer understanding of moral perspectives we disagree with and provides a template for how to influence moral motives and practices in the world.

    Women's health is an often neglected component of health professions education despite the well-documented need to improve the health status of women, especially in low income countries. This paper was written on behalf of all members of The Network: Towards Unity for Health Women and Health Taskforce (WHTF) which unites leaders in women's health and higher education from different countries around the world. The WHTF objectives include teaching health providers the skills and knowledge necessary to improve care to women; encouraging universities to partner with community women's groups; promoting the inclusion of women's rights and gender issues in curricula; and cultivating leadership among female health professions students. The main goal of the paper is to provide an overview of the collaborative processes, the accomplishments and the lessons learned in this project since the early 1990s. It includes the history and evolution of the Taskforce; the importance of human rights and gender issues in approaching women's health; teaching tools--the Women and Health Learning Package (WHLP); implementation of WHLP in health professions education and community settings; and main outcomes and future challenges. The WHLP was implemented in fourteen universities and seven university community programs. A new edition of WHLP will be available in 2009. The WHTF is a model of south-south collaboration in health professions education and community programs to improve women's health. It has been successful in reaching universities and communities all over the globe and provides a model for other education, health and community issues.

  11. Diagonal Eigenvalue Unity (DEU) code for spectral amplitude coding-optical code division multiple access

    Ahmed, Hassan Yousif; Nisar, K. S.

    2013-08-01

    Code with ideal in-phase cross correlation (CC) and practical code length to support high number of users are required in spectral amplitude coding-optical code division multiple access (SAC-OCDMA) systems. SAC systems are getting more attractive in the field of OCDMA because of its ability to eliminate the influence of multiple access interference (MAI) and also suppress the effect of phase induced intensity noise (PIIN). In this paper, we have proposed new Diagonal Eigenvalue Unity (DEU) code families with ideal in-phase CC based on Jordan block matrix with simple algebraic ways. Four sets of DEU code families based on the code weight W and number of users N for the combination (even, even), (even, odd), (odd, odd) and (odd, even) are constructed. This combination gives DEU code more flexibility in selection of code weight and number of users. These features made this code a compelling candidate for future optical communication systems. Numerical results show that the proposed DEU system outperforms reported codes. In addition, simulation results taken from a commercial optical systems simulator, Virtual Photonic Instrument (VPI™) shown that, using point to multipoint transmission in passive optical network (PON), DEU has better performance and could support long span with high data rate.

    A new two dimensional Diagonal Eigenvalue Unity (2D-DEU) code is developed for the spectral⧹spatial optical code division multiple access (OCDMA) system. It has a lower cross correlation value compared to two dimensional diluted perfect difference (2D-DPD), two dimensional Extended Enhanced Double Weight (2D-Extended-EDW) codes. Also, for the same code length, the number of users can be generated by the 2D-DEU code is higher than that provided by the others codes. The Bit Error Rate (BER) numerical analysis is developed by considering the effects of shot noise, phase induced intensity noise (PIIN), and thermal noise. The main result shows that BER is strongly affected by PIIN for the higher source power. The 2D-DEU code performance is compared with 2D-DPD, 2D-Extended-EDW and two dimensional multi-diagonals (2D-MD) codes. This comparison proves that the proposed 2D-DEU system outperforms the related codes.

    Full Text Available Parlare di Pareto, oggi, significa occuparsi di un classico della sociologia che è stato oggetto di una ricezione/recezione discontinua, non solo in Europa ma anche, forse soprattutto, in America. Se negli anni Venti James Harvey Robinson scriveva che la teoria dei residui e delle derivazioni di Pareto si poteva annoverare tra le grandi scoperte scientifiche, è anche vero che la figura di Pareto ha suscitato riserve e perplessità, e che i suoi meriti «furono riconosciuti soltanto dieci anni dopo la sua morte, e per di più in America» (Coser [1977] 1983, p. 582, in particolare ad Harvard (Femia, Marshall 2012. Si pensi ad esempio a Parsons, che negli anni Trenta, ne La struttura dell’azione sociale, richiama ampiamente Pareto (Parsons [1937] 1968, o anche a Merton, il quale, sebbene non sia stato mai molto attratto dalle analisi paretiane (cfr.

Successivamente, però, questo interesse si è fortemente ridimensionato, per poi riaccendersi negli anni Cinquanta e Sessanta, non solo in America ma anche in Europa, come testimoniato, fra l’altro, dall’attenzione riservata a Pareto da Raymond Aron ([1967] 1989.

    Electronic portal imaging devices (EPIDs) are frequently used in external beam radiation therapy for dose verification purposes. The aim of this study was to investigate the dose-response characteristics of the EPID in the Unity MR-linac (Elekta AB, Stockholm, Sweden) relevant for dosimetric applications under clinical conditions. EPID images and ionization chamber (IC) measurements were used to study the effects of the magnetic field, the scatter generated in the MR housing reaching the EPID, and inhomogeneous attenuation from the MR housing. Dose linearity and dose rate dependencies were also determined. The magnetic field strength at EPID level did not exceed 10 mT, and dose linearity and dose rate dependencies proved to be comparable to that on a conventional linac. Profiles of fields, delivered with and without the magnetic field, were indistinguishable. The EPID center had an offset of 5.6 cm in the longitudinal direction, compared to the beam central axis, meaning that large fields in this direction will partially fall outside the detector area and not be suitable for verification. Beam attenuation by the MRI scanner and the table is gantry angle dependent, presenting a minimum attenuation of 67% relative to the 90° measurement. Repeatability, observed over two months, was within 0.5% (1 SD). In order to use the EPID for dosimetric applications in the MR-linac, challenges related to the EPID position, scatter from the MR housing, and the inhomogeneous, gantry angle-dependent attenuation of the beam will need to be solved.

    This project centres on the development of a virtual nuclear facility environment to assist non-proliferation and nuclear arms control practitioners - including researchers, negotiators, or inspectors - in developing and refining a verification system and secure chain of custody of material or equipment. The platform for creating the virtual facility environment is the Unity 3D game engine. This advanced platform offers both the robust capability and flexibility necessary to support the design goals of the facility. The project also employs Trimble SketchUp and Blender 3D for constructing the model components. The development goal of this phase of the project was to generate a virtual environment that includes basic physics in which avatars can interact with their environment through actions such as picking up objects, operating vehicles, dismantling a warhead through a spherical representation system, opening/closing doors through a custom security access system, and conducting CCTV surveillance. Initial testing of virtual radiation simulation techniques was also explored in preparation for the next phase of development. Some of the eventual utilities and applications for this platform include: 1. conducting live multi-person exercises of verification activities within a single, shared virtual environment, 2. refining procedures, individual roles, and equipment placement in the contexts of non-proliferation or arms control negotiations 3. hands on training for inspectors, and 4. a portable tool/reference for inspectors to use while carrying out inspections. This project was developed under the Multilateral Verification Project, led by the Verification Research, Training and Information Centre (VERTIC) in the United Kingdom, and financed by the Norwegian Ministry of Foreign Affairs. The environment was constructed at the Vienna Center for Disarmament and Non-Proliferation (VCDNP). (author)

  2. A kinetic model of droplet heating and evaporation: Effects of inelastic collisions and a non-unity evaporation coefficient

    KAUST Repository

    Sazhin, Sergei S.

    2013-01-01

    The previously developed kinetic model for droplet heating and evaporation into a high pressure air is generalised to take into account the combined effects of inelastic collisions between molecules in the kinetic region, a non-unity evaporation coefficient and temperature gradient inside droplets. It is pointed out that for the parameters typical for Diesel engine-like conditions, the heat flux in the kinetic region is a linear function of the vapour temperature at the outer boundary of this region, but practically does not depend on vapour density at this boundary for all models, including and not including the effects of inelastic collisions, and including and not including the effects of a non-unity evaporation coefficient. For any given temperature at the outer boundary of the kinetic region the values of the heat flux are shown to decrease with increasing numbers of internal degrees of freedom of the molecules. The rate of this decrease is strong for small numbers of these degrees of freedom but negligible when the number of these degrees exceeds 20. This allows us to restrict the analysis to the first 20 arbitrarily chosen degrees of freedom of n-dodecane molecules when considering the effects of inelastic collisions. The mass flux at this boundary decreases almost linearly with increasing vapour density at the same location for all above-mentioned models. For any given vapour density at the outer boundary of the kinetic region the values of the mass flux are smaller for the model, taking into account the contribution of internal degrees of freedom, than for the model ignoring these degrees of freedom. It is shown that the effects of inelastic collisions lead to stronger increase in the predicted droplet evaporation time in Diesel engine-like conditions relative to the hydrodynamic model, compared with the similar increase predicted by the kinetic model considering only elastic collisions. The effects of a non-unity evaporation coefficient are shown to be

    Crude prevalence rates of spondylolysis were estimated in skeletal populations from various periods. There was a steady increase in prevalence from 3.74% in Romano-British to 5.08% in medieval populations, but the rate fell considerably to 1.42% in a population from an 18th/19th century context. This trend was not statistically significant, however. The male/female ratio was approximately unity until the 18th/19th century when the expected male excess appeared. The lesions predominantly affected L5 and all were isthmic in type. Of the total of 52 cases, only four were unilateral. One occurred in the fourth cervical vertebra. There were few complications; spondylolisthesis was noted in four cases and in three there were osteoarthritic changes on the superior margin of the displaced lamina. PMID:1941859

    The main objective of this paper is to discuss on the effectiveness of visualising terrain draped with Unmanned Aerial Vehicle (UAV) images generated from different contour intervals using Unity 3D game engine in online environment. The study area that was tested in this project was oil palm plantation at Sintok, Kedah. The contour data used for this study are divided into three different intervals which are 1m, 3m and 5m. ArcGIS software were used to clip the contour data and also UAV images data to be similar size for the overlaying process. The Unity 3D game engine was used as the main platform for developing the system due to its capabilities which can be launch in different platform. The clipped contour data and UAV images data were process and exported into the web format using Unity 3D. Then process continue by publishing it into the web server for comparing the effectiveness of different 3D terrain data (contour data) draped with UAV images. The effectiveness is compared based on the data size, loading time (office and out-of-office hours), response time, visualisation quality, and frame per second (fps). The results were suggest which contour interval is better for developing an effective online 3D terrain visualisation draped with UAV images using Unity 3D game engine. It therefore benefits decision maker and planner related to this field decide on which contour is applicable for their task.

    Direct numerical simulations (DNS) of temporally developing shear flames are used to investigate both equation of state (EOS) and unity-Lewis (Le) number assumption effects in hydrocarbon flames at elevated pressure. A reduced Kerosene / Air mechanism including a semi-global soot formation/oxidation model is used to study soot formation/oxidation processes in a temporarlly developing hydrocarbon shear flame operating at both atmospheric and elevated pressures for the cubic Peng-Robinson real fluid EOS. Results are compared to simulations using the ideal gas law (IGL). The results show that while the unity-Le number assumption with the IGL EOS under-predicts the flame temperature for all pressures, with the real fluid EOS it under-predicts the flame temperature for 1 and 35 atm and over-predicts the rest. The soot mass fraction, Ys, is only under-predicted for the 1 atm flame for both IGL and real gas fluid EOS models. While Ys is over-predicted for elevated pressures with IGL EOS, for the real gas EOS Ys's predictions are similar to results using a non-unity Le model derived from non-equilibrium thermodynamics and real diffusivities. Adopting the unity Le assumption is shown to cause misprediction of Ys, the flame temperature, and the mass fractions of CO, H and OH.

    Full Text Available O presente artigo evidencia, por um lado, o mérito da filosofia de Espinosa, pelo fato de haver submetido a oposição das partes e do todo, do corpo e da alma, da matéria e do espírito, à unidade da substância, já que toda parte singular da substância pertence à sua natureza. Por outro lado, destaca a crítica de Feuerbach a Espinosa, porque a filosofia deste é, na verdade, uma filosofia da identidade, que não reconhece, como Hegel também assinala, a substância como espírito e o espírito como substância, e não determina suficientemente a unidade da matéria e do espírito, já que falta a ela a realidade da diferença, da determinidade. Enquanto Espinosa identifica Deus com a natureza (Deus sive natura e, mediante a natureza divina (a substância, supera a contradição de Descartes entre matéria (res extensa e espírito (res cogitans, Feuerbach quer, em oposição ao panteísmo, a diferença entre natureza e Deus (aut Deus aut natura.This article on the one hand offers evidence of Spinoza's philosophical merit due to the fact that he propounded the opposition of substance of parts and whole, body and soul, matter and spirit, to unity of substance, since every single part of substance belongs to nature. And on the other hand it presents Feuerbach's critique of Spinoza since Spinoza's philosophy is in fact an identity philosophy which does not recognize, as Hegel also points out, the substance of spirit and the spirit as substance, and does not clearly determinate the unity of matter and spirit because it lacks the truly aspect of difference, determinacy. While Spinoza identifies God with nature (Deus sive natura and by means of divine nature (substance overcomes Descartes' contradiction between matter (res extensa and spirit (res cogitans, Feuerbach wants, in opposition to pantheism, determine the difference between nature and God (aut Deus aut natura.

  15. Worldview, the credit crisis and the ‘unity of life’. From ‘framework’ to ‘deep commitment’

    Directory of Open Access Journals (Sweden)

    Govert J. Buijs

    2012-10-01

    Full Text Available The term ‘worldview’ harbours different dimensions that are not always clearly distinguished. A worldview can be considered to be a personal matter, but it may also be a more collective phenomenon, as it can manifest itself for example within a certain sphere of life (e.g. politics or economics as a full-blown ideology or a more implicit ‘embedded worldview’. A second distinction can be made between the dimension of a deep, existential commitment and that of an encompassing mental framework, between spiritual inspiration and a more or less intellectually coherent system. There may be tensions between these various dimensions. Having a worldview as a person may imply being in conflict with other worldviews that are embodied in certain social fields. How can people deal with these conflicts? One can easily be seduced to avoid the conflicts and to shift gears between them. With the credit crisis and economics used as an illustration, this article explores some of the techniques that people – consciously, semi-consciously or unconsciously – may employ to navigate the differences between various social domains and their inherent worldviews. In order to support people to regain some unity, the notion of worldview may still be helpful, but interpreted primarily as ‘deep commitment’.

    Full Text Available For starting a long term programmes in Croatian animal production, formation of "economic unities" is necessary. Presentation and explanation of production and trade unity for animal production and marketing with subjects and phases is given here. It is pointed out that production of slaughter animals and meat is key interest of market and economic policy as well as of development of agricultural country. It seems that production and trade of meat in Croatia is not organized enough in overall market competition and in meat processing. Creating the economic unity of production and trade of slaughter animals can help in relative fast and efficient solving of problems accumulated in agriculture, especialy in meat production (PIK Vrbovec, Danica, Bejle etc. For initiating and getting in function the phases of production and trade of slaughter animals and meat, proper legislation should be introduced. This legislation should comprehencively define the idea of agricultural economy as a subject of legislative and normisation acts for overall, process and market oriented functioning of multidisciplinary agricultural systems. Additionaly, law on trade of slaughter animals, meat and agricultural products should be introduced in order to form a market and determine the share and obligations of certain participants in structure of such market.

    2016-02-01

    Full Text Available The article seeks to explore the relationship between procurement in the public sector and corruption. Corruption in the procurement process is one of the biggest challenges facing the South Africa government. Procurement in the South African public sector through the tendering process has been used with a particular aim of addressing the past discriminatory practices and policies by empowering the previously disadvantaged majority. It ought to operate within a certain legislative and regulatory framework. However, the article argues that in the process of implementing the good intentions of the government, corruption illegitimises the process. There are also challenges that are associated with public sector procurement, with corruption being the main protagonist. The article also seeks to suggest possible solutions that could be used to address the anomalies. The article further concludes that the main reason for the rife corruption in the public sector is that there is nonadherence to policy prescripts including the Public Finance Management Act, 1999 (Act 1 of 1999 and the Municipal Finance Management Act, 2003 (Act 56 of 2003. This enormous predicament may only be addressed if the government were to show will and commitment by punishing offenders who do not comply with the said legislative framework.

  5. Art and Science the Inseparable Tools of Effective Outreach

    Science.gov (United States)

    Brumfitt, A.; Thompson, L.

    The traditional view in outreach activities is to perceive space and planetary science in education as belonging to two main user groups; primary school, where space is explored as a thematic topic at a simple level, and upper secondary school where it comes into its own as a subject domain in astronomy, cosmology or as a small optional extension of a wider physics curriculum. However the arts (the wider humanities) and the sciences are closely bound together, both historically and in education practice. Traditionally men of science were also men of art and poetry and culture. They were rational and enlightened scholars. Astronomy and planetary science have not lost any of this value in modern education terms. It as relevant today to the performing arts, to history, geography, literature and language as it always has been. Historically it is only recently that sciences and arts have grown formally apart. Astronomy and space appears across the breadth and depth of formal and `hidden' curricula. It supports knowledge and skill bases; it is relevant to every subject from religion to international relations; it is evident in all manner of hands-on and field visit activities and is practiced in all countries. Using a multi disciplinary approach will increase the effectiveness of any outreach effort by a hundred fold. This paper describes the mutuality between the arts and the sciences as practiced in education; it highlights classroom interconnectivity between subject disciplines, knowledge and skill bases; it illustrates approaches and techniques for utilising surprising opportunities within formal and informal fields that considerably enhance outreach effort. It acknowledges the already heavy work load of the scientist and the very real constraints of time, mandates, resources, finance; it provides realistic methods, techniques and opportunities for the noneducation specialist to offer a wider exciting outreach and education programme.

    The coastal population of British Columbia is projected to increase by a million people over the next 20 years. Population growth in the region will increase pressure on the environment through land-use changes and water demand, and the discharge of wastes and pollutants. Changes to the environment will have an impact on industries such as forestry, fishing, and tourism that depend on healthy ecosystems. Six technical papers were presented in this volume as part of a project reporting on the coastal environment of British Columbia. The volume was compiled to help in the future-decision making processes in the province. Reporting for the project focused on a region extending westward from the height of the Coast Mountains, and included the marine area within Canada's 200-mile limit. Papers were presented on the following topics: (1) population and economic activity; (2) climate change; (3) industrial contaminants; (4) ecosystem protection; (5) bio-diversity; and (6) fisheries. Each of the 6 papers provided an overview of issues related to their topic, a set of indicators, and a summary of results. refs., tabs., figs

  7. Superconductivity and fusion energy—the inseparable companions

    2015-02-01

    Although superconductivity will never produce energy by itself, it plays an important role in energy-related applications both because of its saving potential (e.g., power transmission lines and generators), and its role as an enabling technology (e.g., for nuclear fusion energy). The superconducting magnet’s need for plasma confinement has been recognized since the early development of fusion devices. As long as the research and development of plasma burning was carried out on pulsed devices, the technology of superconducting fusion magnets was aimed at demonstrations of feasibility. In the latest generation of plasma devices, which are larger and have longer confinement times, the superconducting coils are a key enabling technology. The cost of a superconducting magnet system is a major portion of the overall cost of a fusion plant and deserves significant attention in the long-term planning of electricity supply; only cheap superconducting magnets will help fusion get to the energy market. In this paper, the technology challenges and design approaches for fusion magnets are briefly reviewed for past, present, and future projects, from the early superconducting tokamaks in the 1970s, to the current ITER (International Thermonuclear Experimental Reactor) and W7-X projects and future DEMO (Demonstration Reactor) projects. The associated cryogenic technology is also reviewed: 4.2 K helium baths, superfluid baths, forced-flow supercritical helium, and helium-free designs. Open issues and risk mitigation are discussed in terms of reliability, technology, and cost.

    Over the course of the past two decades, quantum mechanical calculations have emerged as a key component of modern materials research. However, the solution of the required quantum mechanical equations is a formidable task and this has severely limited the range of materials systems which can be investigated by such accurate, quantum mechanical means. The current state of the art for large-scale quantum simulations is the planewave (PW) method, as implemented in now ubiquitous VASP, ABINIT, and QBox codes, among many others. However, since the PW method uses a global Fourier basis, with strictly uniform resolution at all points in space, and in which every basis function overlaps every other at every point, it suffers from substantial inefficiencies in calculations involving atoms with localized states, such as first-row and transition-metal atoms, and requires substantial nonlocal communications in parallel implementations, placing critical limits on scalability. In recent years, real-space methods such as finite-differences (FD) and finite-elements (FE) have been developed to address these deficiencies by reformulating the required quantum mechanical equations in a strictly local representation. However, while addressing both resolution and parallel-communications problems, such local real-space approaches have been plagued by one key disadvantage relative to planewaves: excessive degrees of freedom (grid points, basis functions) needed to achieve the required accuracies. And so, despite critical limitations, the PW method remains the standard today. In this work, we show for the first time that this key remaining disadvantage of real-space methods can in fact be overcome: by building known atomic physics into the solution process using modern partition-of-unity (PU) techniques in finite element analysis. Indeed, our results show order-of-magnitude reductions in basis size relative to state-of-the-art planewave based methods. The method developed here is

    Florian Greiner

    2014-02-01

    Full Text Available This paper argues that the communication of European integration by the media did not begin with the European unification process after 1950. It draws upon a broad definition of the term “European integration” favoured by modern historiography, and in so doing shows that in the first half of the 20th century journalists communicated various notions of the unity of Europe to their readers. By linking media history and discourse analysis, the article examines three different facets of mediating European integration in German, British and American newspapers between 1914 and 1945. It traces “integrational thinking” in press coverage in three different sectors in particular, namely politics, economy and culture. Although discourses on continental unity were of course ambivalent and far from pointing straight towards European integration in the sense of a present-day European Union, they played an important role in the age of the World Wars. The article thus conceptualises a long-term historical perspective on communicating European integration.

    Hypospadias is a common congenital malformation. Surgical repair and management of the long-term consequences require a substantial amount of socioeconomic resources. It is generally accepted that genetic and environmental factors play a major role in the etiology of hypospadias. There have been contradictory reports on rising hypospadias rates, and regional and ethnical differences. The exact prevalence of hypospadias is of major interest for healthcare providers, clinical medicine, and research. To review the literature regarding the worldwide prevalence of hypospadias. Pubmed, EMBASE and Google were systematically screened for: hypospadias, congenital malformation, anomaly, incidence, prevalence, and epidemiology. Exclusion criteria were surgical and risk-factor studies. To give an additional comprehensive overview, prevalence data were harvested from the Annual Report of the International Clearinghouse Centre for Birth Defects Surveillance and Research. Prevalence was reported as per 10,000 live births. Data were available from 1910 to 2013. The median study period was 9 years (range: 1-36 years). Approximately 90,255,200 births have been screened in all studies. The mean prevalence were: Europe 19.9 (range: 1-464), North America 34.2 (6-129.8), South America 5.2 (2.8-110), Asia 0.6-69, Africa 5.9 (1.9-110), and Australia 17.1-34.8. There were major geographical, regional, and ethnical differences, with an extreme heterogeneity of published studies. Numerous studies showed an increasing prevalence; on the other hand, there were a lot of contradictory data on the prevalence of hypospadias. The summary table shows contradictory data from the five largest international studies available. There was huge literature available on the prevalence of hypospadias. Most data derived from Europe and North America. Many methodological factors influenced the calculation of an accurate prevalence, and even more of the true changes in prevalence over time (no generally accepted

    Full Text Available El artículo se ocupa de la pasión de Leopoldo Zea por la unidad de América Latina, la que es compartida por el autor del trabajo. Dicha pasión se pone de manifiesto tanto en las tesis sostenidas y ahondadas por Zea en sucesivas obras, como en las políticas culturales a las que dio impulso. Una de esas tesis es la tipicidad de la conciencia del hombre americano, pues Zea siempre entendió su filosofar como un pensamiento acerca de la conciencia y su relación, negativa o positiva con lo histórico. Una de las vías decisivas para poder responder positivamente al problema de la unidad continental, deriva del modo como aquella conciencia se objetiva, que da lugar a otra de las tesis zeanianas consistente en la denuncia de una conciencia defectiva, extraña a toda marcha dialéctica e incapaz de alcanzar sucesivas síntesis. La cual tiene también sus riesgos en cuanto a la pretensión de "partir de cero», que Zea denuncia. Otra de las tesis alude a la relación entre filosofía de la historia y filosofía latinoamericana, marco en el cual se comprende la pasión por la unión de nuestra América.This article is about Leopoldo Zea's passion for the unity of Latin America, the one that is shared by the author of this work. This passion is shown in theses that Zea stated in successive works as well as in the cultural policies to which he gave impulse. One of his theses is the typical character of the American man's conscience, because Zea always understood his own philosophy as a way of thinking about the conscience and its positive or negative relation to history. One decisive approach to give a positive response to the question of the continental unity is to consider how that conscience analyzes itself objectively. This gives origin to another of his thesis: this is a flawed conscience, alien to any dialectics and incapable to reach successive syntheses, which also faces the risk of "starting from scratch" that Zea exposes.

    Full Text Available http://dx.doi.org/10.5007/1677-2954.2008v7n2p137This paper systematically discusses Kant´s argumentation in the Canon of the Critique of pure reason on the matter of the establishment of the practical use and its outcomes for the problem of the unity of reason. Bearing in mind that there is much disagreement in the literature, not only as to the specificity and function of the chapter of the Canon wi thin the various moments of Kant´s philosophy, but also as to its critical importance, the approach centers essentially on Kant´s own argumentation. The aim of this paper is to show that the Canon anticipates an important thesis of the Critique of Practical Reason, i.e., the self-sufficient legitimation of the practical use of reason in relation to its theoretical use, Moreover, is demonstrated that there are important systenatic differences between Kant´s argumentation in the Canon and in the second Critique, which lead to the uniqueness of the treatment of the problem of the unity of reason in the former text. The first part of the paper briefly presents Kant´s position in the pre-critical period on the legitimation of the practical use of reason. Thereafter, it is sustained that Kant´s search in the Canon for a "source of positive cognition" is particularly connected with his critical thesis of a self-sufficient establishment in the Canon. It is argued that, notwithstanding the anticipation of the refered critical thesis, the establishment of the practical use of reason in the Canon requires a theological consideration of morality. The third part of the paper deals with the problem of the unity of theorical and practical uses of reason in position on the establishment of the practical use reason. I come to the conclusion that the Canon guaranteed by means of a transition from the practical to the theoretical use of reason.

  15. Amblyopia risk factor prevalence.

    Arnold, Robert W

    2013-01-01

    In 2003, the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) published a set of risk factors for amblyopia. The intent was to promote uniformity of reporting and development in screening. Because this prevalence is not yet known, this meta-analysis is an attempt to estimate it. Major community preschool eye examination studies were reviewed and AAPOS cut-offs estimated. The approximate prevalence of anisometropia is 1.2%, hyperopia is 6%, astigmatism is 15%, myopia is 0.6%, strabismus is 2.5%, and visual acuity less than 20/40 is 6%. The mean combined prevalence is 21% ± 2% compared to a prevalence of amblyopia 20/40 and worse of 2.5%. Knowing risk factor prevalence simplifies validation efforts. Amblyopia screening with a risk factor sensitivity less than 100% is expected and desirable. Copyright 2013, SLACK Incorporated.

  16. Bidentate Ligand-passivated CsPbI3 Perovskite Nanocrystals for Stable Near-unity Photoluminescence Quantum Yield and Efficient Red Light-emitting Diodes

    Although halide perovskite nanocrystals (NCs) are promising materials for optoelectronic devices, they suffer severely from chemical and phase instabilities. Moreover, the common capping ligands like oleic acid and oleylamine that encapsulate the NCs will form an insulating layer, precluding their utility in optoelectronic devices. To overcome these limitations, we develop a post-synthesis passivation process for CsPbI3 NCs by using a bidentate ligand, namely 2,2’-Iminodibenzoic acid. Our passivated NCs exhibit narrow red photoluminescence with exceptional quantum yield (close to unity) and substantially improved stability. The passivated NCs enabled us to realize red light-emitting diodes (LEDs) with 5.02% external quantum efficiency and 748 cd/m2 luminance, surpassing by far LEDs made from the non-passivated NCs.

    carotid sinus hypersensitivity (CSH) is associated with syncope, drop attacks and unexplained falls in older people. However, a recent study has also reported a prevalence of 35% in asymptomatic community-dwelling older people. we conducted a retrospective observational study to investigate the haemodynamic and symptom responses of a large cohort of patients undergoing carotid sinus massage (CSM). the electronically stored haemodynamic data of 302 consecutive patients, aged 71 +/- 11 years, investigated with CSM for unexplained falls and syncope was analysed. Bilateral sequential CSM was performed in the supine and upright positions with continuous electrocardiogram (ECG) and non-invasive beat-to-beat blood pressure monitoring (Taskforce, CN Systems, Austria). CSH (CSH) was defined by maximal R-R interval > or =3 s (cardioinhibitory) and/or a systolic blood pressure drop of > or =50 mmHg (vasodepressor). a total of 74/302 (25%) subjects had CSH, 37 (50%) of which were cardioinhibitory (CI) and 37 (50%) were vasodepressor (VD) subtypes. Subjects with positive CSM were significantly older (75.2 vs 70.2 years, P older individuals. This discrepancy may be explained by selection bias and demographic differences, but raises the possibility of CSH being an age-related epiphenomenon rather than a causal mechanism for syncope, drop attacks and unexplained falls. Our observations have important implications for clinical practice and the development of future research strategies.

    Steep-slope transistors allow to scale down the supply voltage and the energy per computed bit of information as compared to conventional field-effect transistors (FETs), due to their sub-60 mV/decade subthreshold swing at room temperature. Currently pursued approaches to achieve such a subthermionic subthreshold swing consist in alternative carrier injection mechanisms, like quantum mechanical band-to-band tunneling (BTBT) in Tunnel FETs or abrupt phase-change in metal-insulator transition (MIT) devices. The strengths of the BTBT and MIT have been combined in a hybrid device architecture called phase-change tunnel FET (PC-TFET), in which the abrupt MIT in vanadium dioxide (VO 2 ) lowers the subthreshold swing of strained-silicon nanowire TFETs. In this work, we demonstrate that the principle underlying the low swing in the PC-TFET relates to a sub-unity body factor achieved by an internal differential gate voltage amplification. We study the effect of temperature on the switching ratio and the swing of the PC-TFET, reporting values as low as 4.0 mV/decade at 25 °C, 7.8 mV/decade at 45 °C. We discuss how the unique characteristics of the PC-TFET open new perspectives, beyond FETs and other steep-slope transistors, for low power electronics, analog circuits and neuromorphic computing.

    Textbook-like device characteristics are demonstrated in vertical GaN p-n diodes grown on bulk GaN substrates. These devices show simultaneously an avalanche breakdown voltage (BV) of >1.4 kV under reverse bias, an ideality factor plateau of ˜2.0 in a forward bias window followed by a near unity ideality factor of 1.1, which are consistently achieved over a temperature range of 300-400 K. At room temperature (RT), the diode with a mesa diameter of 107 μm showed a differential on-resistance Ron of 0.12 mΩcm2, thus resulting in a record figure-of-merit BV2/Ron of ˜16.5 GW/cm2, which is the highest ever demonstrated in any semiconductors. Analytical models are used to fit experimental I-Vs; based on the recombination current with an ideality factor of ˜2.0, a Shockley-Read-Hall lifetime of 12 ns is extracted at RT with an estimated recombination center concentration of 3 × 1015 cm-3.

    Luminescent pincer-type Pt(II)  complexes supported by C-deprotonated π-extended tridentate RC^N^NR' ligands and pentafluorophenylacetylide ligands show emission quantum yields up to almost unity. Femtosecond time-resolved fluorescence measurements and time-dependent DFT calculations together reveal the dependence of excited-state structural distortions of [Pt(RC^N^NR')(CC-C6 F5 )] on the positional isomers of the tridentate ligand. Pt complexes [Pt(R-C^N^NR')(CC-Ar)] are efficient photocatalysts for visible-light-induced reductive CC bond formation. The [Pt(R-C^N^NR')(CC-C6 F5 )] complexes perform strongly as phosphorescent dopants for green- and red-emitting organic light-emitting diodes (OLEDs) with external quantum efficiency values over 22.1 %. These complexes are also applied in two-photon cellular imaging when incorporated into mesoporous silica nanoparticles (MSNs). © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    In this work, a teepee-like photonic crystal (PC) structure on crystalline silicon (c-Si) is experimentally demonstrated, which fulfills two critical criteria in solar energy harvesting by (i) its Gaussian-type gradient-index profile for excellent antireflection and (ii) near-orthogonal energy flow and vortex-like field concentration via the parallel-to-interface refraction effect inside the structure for enhanced light trapping. For the PC structure on 500-μm-thick c-Si, the average reflection is only ∼0.7% for λ = 400-1000 nm. For the same structure on a much thinner c-Si ( t = 10 μm), the absorption is near unity (A ∼ 99%) for visible wavelengths, while the absorption in the weakly absorbing range (λ ∼ 1000 nm) is significantly increased to 79%, comparing to only 6% absorption for a 10-μm-thick planar c-Si. In addition, the average absorption (∼94.7%) of the PC structure on 10 μm c-Si for λ = 400-1000 nm is only ∼3.8% less than the average absorption (∼98.5%) of the PC structure on 500 μm c-Si, while the equivalent silicon solid content is reduced by 50 times. Furthermore, the angular dependence measurements show that the high absorption is sustained over a wide angle range (θinc = 0-60°) for teepee-like PC structure on both 500 and 10-μm-thick c-Si.

    For Frye, the history of ideas is characterized by sets of opposing views which result in repeated cyclical movements in that history. In this study, Brian Russell Graham argues that Frye's own thinking transcends the ordinary history of ideas and offers what might be thought of as a dialectical...... and `suprahistorical' alternative. As Graham points out, much of Frye's thought is focused on secular concerns, and, within that context, his dialectical and `suprahistorical' thinking is `post-partisan,' a feature which also signifies and explains Frye's appeal. Graham contends it is the thinking of William Blake......, specifically his conceptions of innocence and experience, which provides the inspiration for Frye's dialectical thinking. Graham systematically addresses the main areas of Frye's work: Blake's poetry, secular literature, education and work, politics, and Scripture. In following each of these themes...

    Full Text Available Congenital malformation (CM will begin to emerge as one of the major childhood health problems .Treatment and rehabilitation of children with congenital malformations are costly and complete recovery is usually impossible. The aim of this study was to determine frequency of CM in Yazd central city of the Islamic Republic of Iran to find out if there has been any difference in the rate and types of CM in this area. This descriptive-observational study carried on 4800 births delivered at all maternity hospitals in Yazd from October 2003 to June 2004. Prevalence of CM was 2.83% (2.86 % in male and 2.68 % in female out of the 136 cases 69(51.88% were males and 64 (48.12% were females and 3 with ambiguous genitalia. Positive family history of CM in sibling was in only 6 cases (4.41%.Overall, musculoskeletal (0.83%, central nerv-ous system (0.47% and genital system (0.37% were accounted as the most common. Frequency of CM was more seen in still birth (12.5% as in comparison to live birth (2.71%. There was not statistical difference be-tween prevalence of CM and neonatal's gender, gestational age, birth order and mother's age, drug ingestion, illness and parental consanguinity. In this study the overall prevalence of congenital malformation among the newborn was higher than those previous reported in Iran and determining the causes of this difference needs more extensive studies.

    Peretz, Isabelle; Vuvan, Dominique T

    2017-05-01

    Congenital amusia (commonly known as tone deafness) is a lifelong musical disorder that affects 4% of the population according to a single estimate based on a single test from 1980. Here we present the first large-based measure of prevalence with a sample of 20 000 participants, which does not rely on self-referral. On the basis of three objective tests and a questionnaire, we show that (a) the prevalence of congenital amusia is only 1.5%, with slightly more females than males, unlike other developmental disorders where males often predominate; (b) self-disclosure is a reliable index of congenital amusia, which suggests that congenital amusia is hereditary, with 46% first-degree relatives similarly affected; (c) the deficit is not attenuated by musical training and (d) it emerges in relative isolation from other cognitive disorder, except for spatial orientation problems. Hence, we suggest that congenital amusia is likely to result from genetic variations that affect musical abilities specifically.

    1 The existing prevalence estimates of food additive intolerance(1-4) are being reviewed. 2 In the EEC report the estimated frequency of food additive intolerance is 0.03% to 0.15% based on data from patient groups. 3 The British population study results in a prevalence estimate of 0...... The prevalence estimates vary with a factor 100. As the results vary so do the study populations. 6 If the different study populations are accounted for, a common conclusion can be drawn: Food additive intolerance is found in adults with atopic symptoms from the respiratory tract and skin. The prevalence...... estimates are questionable but may be less than 0.15%. In adults and children with reproducible, and with more subjective symptoms, such as headache and behavioural/mood change the prevalence is even lower (0.026%).

    Full Text Available Increasing evidence suggests that binge eating-related disorders could be related to addiction-like eating patterns due to the addictive potential of hyperpalatable foods. Subsequently, important implications have been derived for treatment of those disorders and even political actions. However, studies on the prevalence of food addiction are rare. Few recent studies investigated addictive eating in children, adolescents, and adults. This mini-review presents these first attempts to assess addictive eating and how prevalent addictive eating patterns were in the respective studies. It is concluded that the prevalence of food addiction is increased in obese individuals and even more so in obese patients with binge eating disorder. However, prevalence of food addiction is not sufficient to account for the obesity epidemic. Conversely, an arguably high prevalence of food addiction can also be found in under-, normal-, and overweight individuals. Future studies may investigate which factors are associated with addictive eating in non-obese individuals.

    Objective: To estimate the prevalence of childhood ataxia resulting from both genetic and acquired causes. Methods: A systematic review was conducted following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) statement. Five databases were searched for articles reporting a frequency measure (e.g., prevalence, incidence) of ataxia in children. Included articles were first grouped according to the World Health Organization (WHO) regions and subsequently classified according to etiology (genetic, acquired, or mixed). Each article was assessed for its risk of bias on the domains of sampling, measurement, and analysis. Incidence values were converted to prevalence estimates whenever possible. European prevalence estimates for different etiologies of ataxia were summed to gauge the overall prevalence of childhood ataxia. Results: One hundred fifteen articles were included in the review. More than 50% of the data originated from the Europe WHO region. Data from this region also showed the least susceptibility to bias. Little data were available for Africa and Southeast Asia. The prevalence of acquired ataxias was found to vary more greatly across regions than the genetic ataxias. Ataxic cerebral palsy was found to be a significant contributor to the overall prevalence of childhood ataxia across WHO regions. The prevalence of childhood ataxias in Europe was estimated to be ∼26/100,000 children and likely reflects a minimum prevalence worldwide. Conclusions: The findings show that ataxia is a common childhood motor disorder with a higher prevalence than previously assumed. More research concerning the epidemiology, assessment, and treatment of childhood ataxia is warranted. PMID:24285620

    The Italian political unification is a process starting in 1861. The next ten years, until the freeing of Rome, are a period of strong changes because the the new nation starts by heavier backwardness conditions compared to other European nations.

    The basic conditionings that bound the new nation are summarized in some causes: an underdeveloped economic system where there are areas of industrial development; a significant shortage of mineral and energy resources; and an urban structure that is still that of the sixteenth century, the last brightness period of the Italian cities. The same internal communication system is composed of a basic road network which is still one of Roman origin and of isolated sections of rail network, with few links among the pre-unity nations.

    Particular attention should be paid on the impact of the economic processes on the cities: they have a strong impact on European cities since the early nineteenth century, but their impact on Italian cities (beginning from the main northern cities, Milan and Turin is more limited, if compared with the transformations concerning other continental cities.

    The unification starting from 1861 imposes additional critical elements, because the Italian urban structure is not ready to the event, particularly for the choice of the capital city. A city that can rightfully define itself as capital exists, and it is Turin; but it is peripheral to the rest of the Italian territory. Furthermore there is an in pectore capital city, Rome, that is the symbolic centre of the Italian history. But the city has to wait another ten years to join to the rest of Italy. The solution is to temporarily move the capitol to Florence, even if nobody explicitly says it to Florentines! The step from Turin to Florence, and from Florence to Rome sets in motion a complex organizational mechanism and a significant money‘s amount, invested in the effort to bring the two cities to the new role

    Observational studies have examined the prevalence and impact of internalized stigma among African American women living with HIV, but there are no intervention studies investigating stigma reduction strategies in this population. Based on qualitative data previously collected, we adapted the International Center for Research on Women's HIV Stigma Toolkit for a domestic population of African American women to be consistent with Corrigan's principles of strategic stigma change. We implemented the intervention, led by an African American woman living with HIV, as a workshop across two afternoons. The participants discussed issues "triggered" by videos produced specifically for this purpose, learned coping mechanisms from each other, and practiced them in role plays with each other. We pilot tested the intervention with two groups of women (total N=24), measuring change in internalized stigma with the Stigma Scale for Chronic Illness before and after workshop participation. Sixty-two percent of the participants self-reported acquiring HIV through heterosexual sexual contact, 17% through intravenous drug use, 4% in utero, and 13% did not know the route of transmission. The intervention was feasible, enthusiastically accepted by the women, and led to decreased stigma from the start of the workshop to the end (p=0.05) and 1 week after (p=0.07) the last session of workshop. Findings suggest the intervention warrants further investigation.

    Abstract Refractive error (RE), particularly myopia, is the first cause of visual impairment throughout the world. This study aimed to depict the prevalence of myopia in a multicentric series of French individuals. This cross-sectional analysis was carried out between January 2012 and November 2013 in eye clinics dedicated to REs. Data collection included age, gender, best-corrected visual acuity, RE, and any relevant medical history involving laser refractive surgery and cataract surgery. Exclusion criteria consisted of monophthalm patients or those with incomplete demographic data. Prevalences in the overall population, by gender and by age groups were reported for mild myopia (−0.50 to −2.75 diopter [D]), moderate myopia (−3 to −5.75 D), high myopia (less than −6 D), and very high myopia (less than −10 D). The analysis included 100,429 individuals, mean age 38.5 years (± 16.9). Overall prevalence of myopia was 39.1% (95% CI 38.8-39.4). Prevalences of mild, moderate, high and very high myopia were respectively 25.1% (95% CI 25.4-24.9), 10.6% (95% CI 10.4-10.8), 3.4% (95% CI 3.3-3.5) and 0.5% (95% CI 0.48-0.57). Even if possible bias occurred in recruitment, our results are similar to RE data collected in nationally representative samples of Caucasians in other studies. This is to our knowledge, one of the largest European series of individuals dedicated to myopia prevalences in different age groups. These results confirm the importance of myopia as a major health issue in Western countries. PMID:26559276

  4. Sustainable development, demography and sexual and reproductive health: inseparable linkages and their policy implications.

    2014-05-01

    The greatest challenge today is to meet the needs of current and future generations, of a large and growing world population, without imposing catastrophic pressures on the natural environment. Meeting this challenge depends on decisive policy changes in three areas: more inclusive economic growth, greener economic growth, and population policies. This article focuses on efforts to address and harness demographic changes for sustainable development, which are largely outside the purview of the current debate. Efforts to this end must be based on the recognition that demographic changes are the cumulative result of individual choices and opportunities, and that demographic changes are best addressed through policies that enlarge these choices and opportunities, with a focus on ensuring unrestricted and universal access to sexual and reproductive health information and services, empowering women to fully participate in social, economic and political life, and investing in the education of the younger generation beyond the primary level. The article provides a strong argument for why the Programme of Action that was agreed at the International Conference on Population and Development (ICPD) 20 years ago continues to hold important implications and lessons for the formulation of the post-2015 development agenda, which is expected to supersede the Millennium Development Goals (MDGs).

    Full Text Available Actualmente estamos sumergidos en un mundo en el cual su principal característica es el cambio constante. Por este motivo, es necesario que el médico sea competente a lo largo de toda su vida profesional. Los adultos aprenden de manera independiente de los profesores y de una forma que está íntimamente ligada a su experiencia. El aprendizaje a lo largo de toda la vida debe ser entendido como un término genérico que incluye e incorpora muchos aspectos o componentes del aprendizaje. Estos aspectos o componentes, cuando se toman juntos, forman un continuo. Este continuo puede verse como una serie o conjunto de actividades de aprendizajes específicos y complementarios, que pueden ser integradas por el médico en momentos diferentes para satisfacer distintos objetivos o prioridades. La motivación de los médicos para participar en el aprendizaje se basa en la necesidad de reducir la tensión creada por la diferencia que existe entre “lo que es” y “lo que debería ser”. Históricamente, la formación médica continuada se ha centrado en las actividades formales; sin embargo, hay muchas más actividades de aprendizaje en el proceso de aprendizaje continuo, tales como: el aprendizaje de adultos, el aprendizaje autodirigido, la reflexión y el aprendizaje en grupos. Todas estas actividades de aprendizaje pueden ayudar a estructurar tipos formales, semiformales e informales de los planes y programas de aprendizaje.

  7. Cyclic Communication and the Inseparability of MIMO Multi-way Relay Channels

    KAUST Repository

    Chaaban, Anas

    2015-10-27

    The K-user MIMO multi-way relay channel (Ychannel) consisting of K users with M antennas each and a common relay node with N antennas is studied in this paper. Each user wants to exchange messages with all the other users via the relay. A transmission strategy is proposed for this channel. The proposed strategy is based on two steps: channel diagonalization and cyclic communication. The channel diagonalization is applied by using zero-forcing beam-forming. After channel diagonalization, the channel is decomposed into parallel sub-channels. Cyclic communication is then applied, where signal-space alignment for network-coding is used over each sub-channel. The proposed strategy achieves the optimal DoF region of the channel if N M. To prove this, a new degrees-of-freedom outer bound is derived. As a by-product, we conclude that the MIMO Y-channel is not separable, i.e., independent coding on separate sub-channels is not enough, and one has to code jointly over several sub-channels.

  8. MYC, Cell Competition, and Cell Death in Cancer: The Inseparable Triad.

    Di Giacomo, Simone; Sollazzo, Manuela; Paglia, Simona; Grifoni, Daniela

    2017-04-17

    Deregulation of MYC family proteins in cancer is associated with a global reprogramming of gene expression, ultimately promoting glycolytic pathways, cell growth, and proliferation. It is well known that MYC upregulation triggers cell-autonomous apoptosis in normal tissues, while frankly malignant cells develop resistance to apoptotic stimuli, partly resulting from MYC addiction. As well as inducing cell-autonomous apoptosis, MYC upregulation is able to trigger non cell-autonomous apoptotic death through an evolutionarily conserved mechanism known as "cell competition". With regard to this intimate and dual relationship between MYC and cell death, recent evidence obtained in Drosophila models of cancer has revealed that, in early tumourigenesis, MYC upregulation guides the clonal expansion of mutant cells, while the surrounding tissue undergoes non-cell autonomous death. Apoptosis inhibition in this context was shown to restrain tumour growth and to restore a wild-type phenotype. This suggests that cell-autonomous and non cell-autonomous apoptosis dependent on MYC upregulation may shape tumour growth in different ways, soliciting the need to reconsider the role of cell death in cancer in the light of this new level of complexity. Here we review recent literature about MYC and cell competition obtained in Drosophila , with a particular emphasis on the relevance of cell death to cell competition and, more generally, to cancer. Possible implications of these findings for the understanding of mammalian cancers are also discussed.

Even if this power was not sufficient, it accelerated the developments changing the balances. In a short time, Italy had become a considered country in the seeking of colonialism after Germany. Italy with Germany forced other western states to follow new strategies and began the first colonial enterprise with Ethiopia, but this independent country has not been able to become colonize. Italy undertook to gain a place in European politics with the Treaty of Triple Alliance in 1882. It began looking for the spreading ways in North Africa and the Balkans. In this article, I focus on that how Italy easily acquired the support of European states through its politics of territory of Ottoman Empire and process of attaining its objective.

    In the 70's a pilot plant for studies of different concentrates processing obtained from the chemical processing of monazite was operated at IPEN / CNEN-SP, with a view to obtaining thorium of nuclear purity. This unity was operated on an industrial scale since 1985, generating around 25 metric tons of residue and was closed in 2002. This waste containing thorium and rare earths was named Retoter (Rejeito de Torio e Terras Raras, in portuguese) and stored in the IPEN Safeguards shed. This paper studies the treatment of the waste, aimed at environmental, radiological and technology. Were studied two cases for the chromatographic separation of thorium from rare earths. One of them was the chromatographic extraction, where the extracting agent tributyl phosphate was supported on polymeric resins Amberlite XAD16. The other method is studied for comparison purposes, since the material used in chromatographic extraction is unprecedented with regard to the separation of thorium, was the ion-exchange chromatography using DOWEX 1-X8 strong cationic resin. Was studied also the chromatographic process of extraction with the extracting agent DEHPA supported on Amberlite XAD16 for the fractionation in groups of rare earths elements. Thorium was separated with high purity for strategic purposes and rare earths recovered free from thorium, were tested as a catalyst for ethanol reforming to hydrogen obtaining which is used in fuel cells for power generation.

  18. Prevalence of obesity in Denmark

    DEFF Research Database (Denmark)

    Due, P; Heitmann, B L; Sørensen, T I A

    2007-01-01

    There has been a pronounced, distinctive increase of the prevalence of obesity within almost all age groups of the Danish population, during the last 25-30 years. The largest increase has been documented in studies based on objective data from total populations and the latest data show the increase...... will continue. The Danish studies show heterogeneity in the development of the obesity epidemic. A close association with birth cohorts indicates a need for further aetiological research, not only into behavioural factors, but also into early life factors that may explain some of this developmental pattern....

    2012-03-01

    Pedophilia is a disorder of sexual preference that increases the risk for committing sexual offenses against children. Consequently, pedophilia is not only relevant in psychiatric therapy and prognostics, but also greatly influences the public attitude towards criminality. Public opinion seems to equate pedophilia with child sexual abuse and vice versa which leads to stigmatization of patients and may impede treatment. The present paper provides information on recent studies on the potential origins of the disorder and introduces new diagnostic methods. Moreover, the article presents estimates on the prevalence of pedophilic sexual interest.

    1998-06-01

    To evaluate the prevalence of cigarette smoking in Cambodia and identify prevailing knowledge, attitudes and practices (KAP). Information on tobacco smoking and KAP was collected using the 30-cluster survey design wherein 10-15 males (age over 15 years) were interviewed from each of 30 randomly-selected population clusters in Phnom Penh (herein referred to as 'urban') and Siem Reap (herein referred to as 'rural') for a total of 601 interviews. Findings show that 65% of urban respondents and 86% of rural respondents smoke. Rural men start smoking at an earlier age, but the average urban smoker spends more. 17% of an urban smoker's personal cash income is spent on tobacco, whereas his rural counterpart spends 8%. This discrepancy is partly due to extensive tobacco brandname promotion in urban areas which has resulted in the average price of a pack of cigarettes being four times higher than that of rural. Other findings show an inverse correlation between incidence of smoking and levels of education/income. Concerning smoking cessation, 66% of urban smokers and 86% of rural smokers interviewed indicated they would attend a program in their area to stop smoking if such a program were available. The high prevalence of smoking in Cambodia, and the health impact it has and will increasingly have on its people is significant. The high cash expenditure for tobacco, especially in urban, is an important factor contributing to Cambodia's impoverished economy. Education, regulatory policies, and smoking cessation are important measures to be considered for effective tobacco control planning and implementation.

  4. 德行一體說對於品格教育的啟示 The Doctrine of the Unity of the Virtues and its Implications for Character Education

    2013-12-01

    Full Text Available 對於以「德行教學」界定品格教育的常見質疑是:品格教育不過是被L.Kohlberg戲稱為「美德袋取徑」的翻版而已。為了消除這項疑慮,必須闡明各德行之間的關係。此論題過去是在具爭議性的「德行一體說」中被探討的。在為一種可信度較高的德行一體說辯護後,筆者歸結出該學說對於當前品格教育的重要啟示,包括:一、既然德行之間的整合是德行教學中必不可少的重要環節,則以分隔化的方式來教導各個德行是有問題的,尚須教導學生處理道德要求多於一種的複雜的道德情境;二、道德氣質的培養以及各德行所需的(評價性)知識的學習,乃是德行涵養的兩個主要任務;最後,「道德人格的多樣化」獲得該學說的支持,亦即,有德的人實際上是各具特色、多樣類型的,「道德品格的個殊化」這項重要議題也因而獲得彰顯。 A doubt often cast on the common practice of defining character education in terms of the inculcation of virtues is that it is simply a duplication of the “bag of virtues” approach, as derogatorily dubbed by L. Kohlberg. To dispel this misgiving, it is imperative to expound the relationship between the virtues, which was addressed in the controversial doctrine of the unity of the virtues in the past. After the author argue for a more plausible interpretation of it, some implications for character education are drawn in this study. Firstly, since the integration of the virtues is integral to the inculcation of virtues, it is problematic to teach the virtues in a compartmentalized way. Instead, it is necessary to learn how to confront a complex moral situation where more than one moral requirement is (are demanded of the moral agent. Secondly, it is made explicit that the cultivation of moral dispositions and the learning of (evaluative knowledge requisite for the various virtues are the two

    All-inorganic perovskites have emerged as a new class of phosphor materials owing to their outstanding optical properties. Zero-dimensional inorganic perovskites, in particular the Cs4PbBr6-related systems, are inspiring intensive research owing to the high photoluminescence quantum yield (PLQY) and good stability. However, synthesizing such perovskites with high PLQYs through an enviromentally friendly, cost-effective, scalable, and high-yield approach remains challenging, and their luminescence mechanisms has been elusive. Here, we report a simple, scalable, room-temperature self-assembly strategy for the synthesis of Cs4PbBr6/CsPbBr3 perovskite composites with near-unity PLQY (95%), high product yield (71%) and good stability, using low-cost, low-toxicity chemicals as precursors. A broad range of experimental and theoretical characterizations suggest that the high-efficiency PL originates from CsPbBr3 nanocrystals well passivated by the zero-dimensional Cs4PbBr6 matrix that forms based on a dissolution-crystallization process. These findings underscore the importance in accurately identifying the phase purity of zero-dimensional perovskites by synchrotron X-ray technique to gain deep insights into the structure-property relationship. Additionally, we demonstrate that green-emitting Cs4PbBr6/CsPbBr3, combined with red-emitting K2SiF6:Mn4+, can be used for the construction of WLEDs. Our work may pave the way for the use of such composite perovskites as highly luminescent emitters in various applications such as lighting, displays, and other optoelectronic and photonic devices.

According to this view, the United States makes financial transfers to foreign countries - military expenditures, government loans, private loans, and direct investment - in amounts which for various reasons it is unable to match with real transfers, that is, with an excess of exports over imports of goods, and services. The author offers additional support for this hypothesis by means of statistical illustration, and points out why the official prescriptions for removing the payments imbalance is useless, or worse.

    2011-01-01

    In recent years there has been a resurgence of interest in the law of public international organizations. This fifth, revised edition of International Institutional Law covers the most recent developments in the field. Although public international organizations such as the United Nations, the World Trade Organization, the World Health Organization, ASEAN, the European Union and other organizations have broadly divergent objectives, powers, fields of activity and numbers of member states, they also share a wide variety of institutional problems. Rather than being a handbook for specific organizations, the book offers a comparative analysis of the institutional law of international organizations. It includes comparative chapters on the rules and practices concerning membership, institutional structure, decision-making, financing, legal order, supervision and sanctions, legal status and external relations. The books theoretical framework and extensive use of case-studies is designed to appeal to both academics ...

  13. On the unity of International Law Theory

    Directory of Open Access Journals (Sweden)

    Pablo J. Martín Rodríguez

    2011-01-01

    Full Text Available It has become a truism that international lawyers are, nowadays, facing a sharp disagreement regarding the main methodological foundations of the discipline. The issue cannot be whether or not there is such a division in the IL school of thought, but which its specific features are. In the present paper, it is submitted here that the current situation is not due to the various methodologies at our disposal, but an actual paradigmatic schism with deep repercussions on the main research agenda. This paradigmatic split steers our attention to the incommensurability of the different paradigms at stake, and consequently the mere possibility of a meaningful communicative interaction between them is dismissed. This picture, though, may be not fully convincing. This multi-paradigmatic state and its ongoing reissue could be seen in a different way, once we accept that neither perfect communication ever obtains nor absolute lack of contradiction is such an epistemological premise. Then, the admittedly existing cross-references, links and overlaps between different approaches can be interpreted not as a paradigmatic mistake (a sort of an internally dysfunctional approach, but as an acknowledgement by each paradigm of its inability to fully explain International Law reality and its openness to alterity, i.e., a recognition of other paradigms as legitimate interlocutors. This interparadigmatic dialogue, that is also noticeable in the main debates on IL structure, shows the most appropriate direction for international lawyers to follow, even if a final paradigmatic converging horizon is not conceivable or even possible.

The question is prepared on a historical view of matter, and in the bordering line of a sense of a essence of things. As a matter of a sense of substance we must have a hermeneutical preparing in a historical dimension, what it is, and after that make a judgment what is not possible to be. Investigations always take us back to the antique period of philosophical researches because there is substance considering without any commas dealing with a strange interests looking from the side of pure philosophy. Beauty, good and a truth still must be a comprehensive values or a super transcendental beings in the sort of lights of a thinking. Thinking is possible if we have adequate ideas on the mind, and that ideas must have a spiritual space for them existing in us, or in the continuing of a life of the history of philosophy as a matter of our aesthetical meanings and a habit of the spirit. By that sign in our awareness mind we take out duty to building self-consciousness, as a personal updating and also take to philosophy that what she asks from us today.

  20. The (dis)unity of nursing science.

    Science.gov (United States)

    Bluhm, Robyn L

    2014-10-01

    This paper looks at the implications of contemporary work in philosophy of science for nursing science. Early work on the nature of theories in nursing was strongly influenced by logical empiricism, and this influence remains even long after nurse scholars have come to reject logical empiricism as an adequate philosophy of science. Combined with the need to establish nursing as an autonomous profession, nursing theory's use of logical empiricism has led to serious conceptual problems. Philosophers of science have also rejected many of the central tenets of logical empiricism, including its focus on the logical justification of theories and the idea that science is, or should be, unified. Instead, there has been an increasing focus on the practice of science, which in turn has led to a pluralist understanding of science that emphasizes the construction of scientific models that are appropriate for certain purposes or in certain contexts. I suggest that this approach to philosophy of science may provide better resources for nursing science. © 2014 John Wiley & Sons Ltd.

    Full Text Available Objective: the aim of this study was to identify the prevalence of constipation in diabetic patients treated at the endocrinology outpatient clinic at Hospital Universitário Professor Alberto Antunes and PAM Salgadinho, from April to August 2013. Methods: a descriptive and cross-sectional study, carried out through a questionnaire using the Rome III criteria in 372 patients treated at the outpatient endocrinology clinic. Results: of 372 patients evaluated, the frequency of constipation found was 31.2% among diabetic patients. Females predominated in the sample (72.8% as well as for the frequency of constipation (80.2%. The incidence of type II diabetes was 97.3% and it was observed that 80.2% of the sample was older than 50 years. One hundred and twelve patients with inadequate glycemic control (HgA1c ≥ 7 had an association with constipation. Conclusion: there was an increased frequency of constipation in patients with diabetes mellitus according to the Rome III criteria, in relation to the general population. The inadequate glycemic control in patients with diabetes mellitus increases the frequency of constipation and it is necessary to perform studies that allow the confirmation of this association to demonstrate this hypothesis.

    Full Text Available Os conflitos políticos e sociais dos últimos anos na Europa, como os com a imigração e o terrorismo, orientam muitas questões levantadas pelas ciências humanas na atualidade. No que se refere à medievalística, muitas obras e projetos europeus apresentam a discussão em torno da diversidade cultural européia, a qual pode ser fundamentada desde a Idade Média através do convívio e trocas culturais entre cristão, judeus e muçulmanos. No centro destas discussões, está a crítica à idéia de centro e periferia dentro da própria Europa e no mundo, além da reflexão sobre conceitos de europeização e africanização, utilizados pela historiografia européia desde a primeira metade do século XX até poucos anos atrás. Neste artigo, serão apresentadas, à luz da Nova História Cultural Alemã (Neue Kulturgeschichte, algumas críticas aos conceitos de europeização, africanização, centro, periferia e unidade cultural na Idade Média européia. Questões estas que acaloram os debates na Alemanha atual.Political and social conflicts during recent years in Europe - such as immigration and terrorism - have guided humanities issues today. Regarding Middle Age research, many works and projects present a debate on European cultural diversity, which lay the foundations since the Middle Ages through interaction and cultural exchanges between Christians, Jews and Muslims. Within the discussion, is the criticism to the idea of center and periphery within Europe itself and the world, as well as the consideration of concepts such as europeanization and africanization, used by European historiography, from the first half of the twentieth century until a few years ago. This article presents criticism to the concepts of europeanization, africanization, center, periphery, and cultural unity in the Middle Ages, in light of the New German Cultural History (Neue Kulturgeschichte, issues that inflame the debate in Germany today.

    The term malnutrition includes malnutrition due to excess or obesity, underweight as well as stunted growth. Its prevalence in a population can be estimated using anthropometric variables. The aim of this study is to estimate the prevalence of malnutrition in Galician schoolchildren aged 6 to 15years in the school year 2013-2014. A cross-sectional study was conducted on a representative sample by gender and age of the Galician population of 6 to 15years old. The prevalence of obesity, underweight, and short stature was estimated by age and gender using the reference standards proposed by the World Health Organisation. Of the total of 7,438 schoolchildren weighed and measured, 16.4% had malnutrition. The prevalence of obesity was 14.8%, underweight was 0.7%, and short stature for age was estimated at 1%. Obesity was more prevalent among boys. As regards underweight and short stature, when there were differences, prevalence was higher among girls. In Galicia, 16 out of every 100 schoolchildren aged 6 to 15years had malnutrition, with that due to excess or obesity being the most frequent. Prevalence of underweight and short stature did not exceed 1%. This data shows that primary prevention measures should be promoted at an early age to reduce malnutrition due to excess or adiposity, in particular. Copyright © 2017.

    The present study aimed to update the literature review on the prevalence of fibromyalgia published in 2006. A bibliographical survey was carried out from 2005 to 2014 in the MEDLINE, Web of Science, Embase, LILACS and SciELO databases and 3274 records were identified. Five researchers selected the studies, following the inclusion criteria: studies that obtained the prevalence of fibromyalgia. Fibromyalgia studies in associated diseases were excluded. When screening by title and abstract, 2073 irrelevant articles were excluded. The full texts of 210 articles were evaluated for eligibility and this review included 39 studies, described in 41 articles. The selected studies were grouped into four categories: (A) prevalence of fibromyalgia in the general population; (B) prevalence of fibromyalgia in women; (C) prevalence of fibromyalgia in rural and urban areas; (D) prevalence of fibromyalgia in special populations. The literature shows values of fibromyalgia prevalence in the general population between 0.2 and 6.6%, in women between 2.4 and 6.8%, in urban areas between 0.7 and 11.4%, in rural areas between 0.1 and 5.2%, and in special populations values between 0.6 and 15%. This literature review update shows a significant increase in fibromyalgia prevalence studies in the world. The new 2010 American College of Rheumatology criteria have not been widely used yet and the COPCORD (Community-oriented program for control of Rheumatic Diseases) methodology has increased the quality of studies on the prevalence of rheumatic diseases in general.

  8. Childhood obesity, prevalence and prevention

    2005-09-01

    Full Text Available Abstract Childhood obesity has reached epidemic levels in developed countries. Twenty five percent of children in the US are overweight and 11% are obese. Overweight and obesity in childhood are known to have significant impact on both physical and psychological health. The mechanism of obesity development is not fully understood and it is believed to be a disorder with multiple causes. Environmental factors, lifestyle preferences, and cultural environment play pivotal roles in the rising prevalence of obesity worldwide. In general, overweight and obesity are assumed to be the results of an increase in caloric and fat intake. On the other hand, there are supporting evidence that excessive sugar intake by soft drink, increased portion size, and steady decline in physical activity have been playing major roles in the rising rates of obesity all around the world. Consequently, both over-consumption of calories and reduced physical activity are involved in childhood obesity. Almost all researchers agree that prevention could be the key strategy for controlling the current epidemic of obesity. Prevention may include primary prevention of overweight or obesity, secondary prevention or prevention of weight regains following weight loss, and avoidance of more weight increase in obese persons unable to lose weight. Until now, most approaches have focused on changing the behaviour of individuals in diet and exercise. It seems, however, that these strategies have had little impact on the growing increase of the obesity epidemic. While about 50% of the adults are overweight and obese in many countries, it is difficult to reduce excessive weight once it becomes established. Children should therefore be considered the priority population for intervention strategies. Prevention may be achieved through a variety of interventions targeting built environment, physical activity, and diet. Some of these potential strategies for intervention in children can be

    The prevalence and course of pseudothrombocytopenia in outpatients is uncertain. In a cohort study of 687,955 members of a health maintenance organization, we extracted 36,780 consecutive automated complete blood count test results and determined the point prevalence of pseudothrombocytopenia during a one-month period. We also calculated a retrospective cumulative prevalence over the past 5 years. There were 1105 (2.7%) patients with platelet counts of 100-149×10(9)/L and 304 (0.8%) with counts values, or the reference limit value should be lowered to 100×10(9)/L.

    Prevalence and distribution of dental caries in medieval Korean society were evaluated. Two thousand and nine hundred teeth samples of 126 individuals collected from 16th to 18th century Korean tombs. Preservation status of sample was good. The prevalence of ante- and postmortem tooth loss was 4.4% and 14.2%, respectively. The total caries prevalence was 3.9%. The tooth surface most frequently affected by dental caries was occlusal (4.5%), followed by approximal (2.1%), buccal (1.5%), and lingual (1.1%) surfaces. The prevalence of dental caries in Joseon Dynasty skeleton collection was lower than have been found in other collections of similar chronology. The low consumption of refined sugar in medieval Korean society might be a possible explanation, though the technical limitations inherent in such comparison studies preclude definitive conclusions. 2010 Elsevier Ltd.

    Efraín Amaya Vargas

    Full Text Available With the gradual increase in the life expectancy of the population due to scientific progress and public health at the service of society, the prevalence of dementia has been increasing at different rates worldwide. Currently, the prevalence rates range between 5% and 7% (6.4% in the U.S. and up to 8.5 % in Latin America in subjects older than 60 years. The lowest prevalence rate (2.1% has been reported from sub-Saharan Africa, probably due to selective mortality under 60 years of age. By contrast, a very high prevalence of dementia (23.6% dementia in individuals ≥60 years was observed in the city of Neiva, Southern Colombia. We believe that this high rate could be explained by the presence of several risk factors such as very low schooling, low socio-economic strata, chronic diseases, the inclusion of geriatric homes among others, and additional unknown factors.

    2008-08-01

    To determine the prevalence of vernal keratoconjuntivitis (VKC) in Europe. A cross-sectional survey was mailed to 3003 ophthalmologists from six countries (Finland, France, Italy, The Netherlands, Norway and Sweden) representing 151.9 million inhabitants. Results were analysed per country, and VKC prevalence for the 15 European member states in 2002 was extrapolated. Six hypotheses were used: disease duration (4 or 8 years) combined with three prevalence hypotheses for non-responding ophthalmologists. The response rate to the survey was 29.5%. The estimates of VKC prevalence in Western Europe (per 10,000 inhabitants) ranged from 1.16 to 10.55. The prevalence of VKC with corneal complications ranged from 0.30 to 2.26. The VKC prevalences per country were in the following ranges: Italy 2.4-27.8, Finland, 0.7-8.4, Sweden 1.2-8.7, The Netherlands 0.6-4.6, France 0.7-3.3 and Norway 0.3-1.9. VKC with corneal complications were: Italy 0.4-4.8, Sweden 0.3-2.4, Finland 0.2-2.8, The Netherlands 0.2-1.6, France 0.3-1.4 and Norway 0.1-1.0. Based on the most likely hypotheses concerning disease duration and non-responding ophthalmologists' VKC case rate, the best estimate of VKC prevalence in Western Europe is 3.2/10,000 inhabitants. The prevalence of VKC with corneal complications is 0.8/10,000 inhabitants.

  10. Malaria prevalence in endemic districts of Bangladesh.

    Directory of Open Access Journals (Sweden)

    Ubydul Haque

    Full Text Available BACKGROUND: Following the 1971 ban of DDT in Bangladesh, malaria cases have increased steadily. Malaria persists as a major health problem in the thirteen south-eastern and north-eastern districts of Bangladesh. At present the national malaria control program, largely supported by the Global Fund for AIDS, Tuberculosis and Malaria (GFATM, provides interventions including advocacy at community level, Insecticide Treated Net (ITN distribution, introduction of Rapid Diagnostic Tests (RDT and combination therapy with Coartem. It is imperative, therefore, that baseline data on malaria prevalence and other malaria indicators are collected to assess the effectiveness of the interventions and rationalize the prevention and control efforts. The objective of this study was to obtain this baseline on the prevalence of malaria and bed net use in the thirteen malaria endemic districts of Bangladesh. METHODS AND PRINCIPAL FINDINGS: In 2007, BRAC and ICDDR,B carried out a malaria prevalence survey in thirteen malaria endemic districts of Bangladesh. A multi-stage cluster sampling technique was used and 9750 blood samples were collected. Rapid Diagnostic Tests (RDT were used for the diagnosis of malaria. The weighted average malaria prevalence in the thirteen endemic districts was 3.97%. In five south-eastern districts weighted average malaria prevalence rate was 6.00% and in the eight north-eastern districts weighted average malaria prevalence rate was (0.40%. The highest malaria prevalence was observed in Khagrachari district. The majority of the cases (90.18% were P. falciparum infections. Malaria morbidity rates in five south-eastern districts was 2.94%. In eight north-eastern districts, morbidity was 0.07%. CONCLUSION AND SIGNIFICANCE: Bangladesh has hypoendemic malaria with P. falciparum the dominant parasite species. The malaria situation in the five north-eastern districts of Bangladesh in particular warrants urgent attention. Detailed maps of the

    Oppositional defiant disorder (ODD) is characterized by a pattern of negative, defiant, disobedient and hostile behavior toward authority figures. ODD is one of the most frequent reasons for clinical consultation on mental health during childhood and adolescence. ODD has a high morbidity and dysfunction, and has important implications for the future if not treated early. To determine the prevalence of ODD in schoolchildren aged 6-16 years in Castile and Leon (Spain). Population study with a stratified multistage sample, and a proportional cluster design. Sample analyzed: 1,049. Cases were defined according to DSM-IV criteria. An overall prevalence rate of 5.6% was found (95% CI: 4.2%-7%). Male gender prevalence=6.8%; female=4.3%. Prevalence in secondary education=6.2%; primary education=5.3%. No significant differences by gender, age, grade, type of school, or demographic area were found. ODD prevalence without considering functional impairment, such as is performed in some research, would increase the prevalence to 7.4%. ODD cases have significantly worse academic outcomes (overall academic performance, reading, maths and writing), and worse classroom behavior (relationship with peers, respect for rules, organizational skills, academic tasks, and disruption of the class). Castile and Leon has a prevalence rate of ODD slightly higher to that observed in international publications. Depending on the distribution by age, morbidity and clinical dysfunctional impact, an early diagnosis and a preventive intervention are required for health planning. Copyright © 2013 SEP y SEPB.

    The research aimed to investigate back pain (BP) prevalence in a large cohort of young athletes with respect to age, gender, and sport discipline. BP (within the last 7 days) was assessed with a face scale (face 1-2 = no pain; face 3-5 = pain) in 2116 athletes (m/f 61%/39%; 13.3 ± 1.7 years; 163.0 ± 11.8 cm; 52.6 ± 13.9 kg; 4.9 ± 2.7 training years; 8.4 ± 5.7 training h/week). Four different sports categories were devised (a: combat sports, b: game sports; c: explosive strength sport; d: endurance sport). Analysis was described descriptively, regarding age, gender, and sport. In addition, 95% confidence intervals (CI) were calculated. About 168 (8%) athletes were allocated into the BP group. About 9% of females and 7% of males reported BP. Athletes, 11-13 years, showed a prevalence of 2-4%; while prevalence increased to 12-20% in 14- to 17-year olds. Considering sport discipline, prevalence ranged from 3% (soccer) to 14% (canoeing). Prevalences in weight lifting, judo, wrestling, rowing, and shooting were ≥10%; in boxing, soccer, handball, cycling, and horse riding, ≤6%. 95% CI ranged between 0.08-0.11. BP exists in adolescent athletes, but is uncommon and shows no gender differences. A prevalence increase after age 14 is obvious. Differentiated prevention programs in daily training routines might address sport discipline-specific BP prevalence. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Introduction: Bronchial asthma is common chronic disease among young people and prevalence of this condition has been constantly growing over past two decades throughout the world. Objective: To establish the prevalence of asthma in student population of Belgrade University and to determine the frequency distribution in regard to their permanent residence. Method: Data obtained from annual physical examinations of 118 342 students (age 19-23 years treated at the Student’s Health Care Institute between 1996-2001 were analyzed. Affirmative answer to the question: "Are you currently treated", or "Have you ever been treated for asthma" indicated diagnosis of asthma. Data on student’s age, gender, permanent residence, and smoking habits were collected. Results: The prevalence of asthma was 3680/100.000 and mildly growing trend was noted over the last several years (from 2.96% to 4.05% (F=42.427; df=4; p<0.01. Asthma was more prevalent in females (57% than among males (43% (χ2=91.189; df=1; p<0.01. Several regions with increased asthma incidence were identified and the causes of such findings still need to be clarified. Cigarette smoking was common in students (χ2=236.781; df=1; p<0.01, but also among asthmatics [one out of three students was a smoker (χ2=8.141; df=1; p<0.01]. Conclusion: The prevalence of asthma in student population is 3.68% with mildly growing trend over the last years. The disease is more prevalent in females. Cigarette smoking is common in students as well as among asthmatics. To our knowledge, this is the first study on prevalence of asthma in young adult population in our country.

    To identify the prevalence of hyperhidrosis among medical students of Manaus, State of Amazonas, Brazil. We conducted an observational, transversal, survey which examined the prevalence of primary hyperhidrosis among medical students of the Federal University of Amazonas and its relation to body mass index (BMI) and stress. Students were weighed and interviewed. We used questionnaires with questions recommended by the International Hyperhidrosis Society to relate hyperhidrosis to the daily activities of each person. Results were given by calculating the prevalence ratios and confidence intervals. Among the 293 students examined, it was found that a total of 16 (5.5%) students had barely tolerable or intolerable excessive sweating, interfering with daily activities. None had known causes of hyperhidrosis and 50% had family history. In all suffering from the condition the disease was bilateral, the mainly affected locations being: hands (35.7%), legs (21.4%), axilla (17.9), face (10 7%), back (7.1%), chest (3.6%) and abdomen (3.6%). There was no predominance regarding gender, age or BMI. We found a positive relationship with BMI and observed a prevalence ratio of 2.48 higher in overweight students than in normal weight or underweight ones. The prevalence of primary hyperhidrosis among medical students of Manaus was 5.5%. There is a positive non-statistical relationship with overweight and obesity. It was further noted an observational relationship with stress.

    To determine the prevalence of metabolic syndrome (MS) according to the definitions of the National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III) and the International Diabetes Federation (IDF) and its relation to cardiovascular disease (CVD) in hospitalized elderly patients. This descriptive and prospective study (February-March 2011) included 200 consecutive patients hospitalized in a Geriatric Department. Sociodemographic, clinical and biochemical data was collected. The prevalence of MS was 65% (NCEP-ATP III) and 67.5% (IDF) and was greater in women (NCEP-ATP III=72.8%, IDF=73.6%) than in men (NCEP-ATP III=50.7%; IDF=56.3%). The mean age of patients diagnosed with MS by both diagnostic criteria were similar: 84.7 years. MS was not associated with an increased prevalence of CVD. MS is highly prevalent in elderly hospitalized patients, being higher in women, with both diagnostic criteria (NCEP- ATP III and IDF). In our population the MS was not associated with an increased prevalence of CVD. Copyright © 2013 SEGG. Published by Elsevier Espana. All rights reserved.

    Currently, hyperhomocysteinemia is a well-known risk factor for variety of vascular diseases. Prevalence of hyperhomocysteinemia increases with age. Hence, the present study was aimed to investigate the prevalence of hyperhomocysteinemia in healthy upper socio-economic class population in India. Total homocysteine (tHcy) concentration was determined in 1243 (906 men & 337 women) healthy Indian doctors with different age group. Using Third National Health and Nutrition Examination Survey (NHANES III) study criteria, the prevalence of hyperhomocysteinemia was 92.85% among men (>11.4 µmol/L) and 81.60% among women (>10.4 µmol/L). The prevalence of hyperhomocysteinemia was higher among men with mean tHcy concentration (21.96 ± 0.38 µmol/L) significantly higher (P<0.0001) than women (15.90 ± 0.39 µmol/L) (95% CI, 4.733- 7.376). Our study showed very high prevalence of hyperhomocysteinemia which may point to the future risk for various pathologies in the present subset of population. Further studies to look at the plasma levels of homocysteine lowering vitamins are warranted to prevent the future risk of vascular diseases. PMID:23519236

    Genetic etiology comprises a significant proportion of renal disease in childhood. Completion of the Human Genome Project and increased genetic testing has assisted with the increased recognition of a genetic basis to many renal disorders. Australia and New Zealand have a relatively stable but diverse population, with eight major pediatric nephrology referral centers, which allow ascertainment of disease frequency. To determine prevalence, pediatric nephrologists at the eight centers in Australia and New Zealand were surveyed on their estimated number of patients with renal disease of genetic etiology over a 10-year period. Disease prevalence was calculated using combined national population data. The overall prevalence of genetic kidney disease in children in Australia and New Zealand is 70.6 children per million age-representative population. Congenital anomalies of the kidney and urinary tract (CAKUT) and steroid-resistant nephrotic syndrome (SRNS) are the most frequent, with a prevalence of 16.3 and 10.7, respectively, per million children. We find a similar prevalence of genetic renal disorders in Australia and New Zealand to those reported in other countries. This is likely to be due to inclusion of children with all forms of renal disease rather than being limited to those with renal impairment.

    To evaluate the published medical literature on the prevalence and types of food allergies in South Asia. A PubMed search was performed using the keywords India and food allergy, Asia and food allergy, and South Asia and food allergy for any period. Articles cited in selected studies were reviewed for their appropriateness of inclusion into this review. Publications were included that were original research and fit the topic of food allergy and South Asia. South Asia is defined as region inclusive of India, Pakistan, Bangladesh, and Sri Lanka. A total of 169 articles were initially identified, and 47 were reviewed in detail for inclusion in this review. The primary focus was placed on 10 studies that consisted of case reports of newly reported or documented food allergy, survey studies that investigated food allergy prevalence in specific demographics, and prospective and cross-sectional studies with case controls, all of which investigated food allergy prevalence by allergy testing in a selected population. The medical literature on the prevalence and types of food allergy in South Asia indicates that there is a variety of unusual and unique allergens and an overall low incidence of food allergy. There is also an association of increased food allergy prevalence in individuals who live in metropolitan regions or who migrate to communities that have adopted westernization.

    Burnout is a job-related psychological syndrome with three aspects: emotional exhaustion, depersonalization, and perceived lack of personal accomplishment. Burnout is associated with deleterious effects on both workers and their work. When burnout affects physicians, their well-being, longevity, and care of patients are at risk. Recent studies concerning physician burnout treat specialists such as radiologists as one group. We studied burnout in musculoskeletal (MSK) subspecialist radiologists. An institutional review board exemption was obtained. Society of Skeletal Radiology members received invitations to an anonymous survey that included questions from the Maslach Burnout Inventory trademark (MBI) measuring all three aspects of burnout. The response rate was 36.4% (433/1190). The prevalence of emotional exhaustion was 61.7% (255/413), of depersonalization 53.3% (219/411), and of perceived lack of personal accomplishment 39.6% (161/407). Only 19.5% (79/405) of MSK radiologists reported no burnout, while 80.5% (326/405) reported burnout along one or more dimensions. For all three dimensions, the prevalence was higher and the mean severity was worse for private practice compared with academic practice. The prevalence of burnout was affected more by practice setting than by gender. Burnout prevalence and severity also varied systematically with years since completion of training. Among MSK radiologists, we found a much higher prevalence and greater severity of burnout than has been previously reported for radiologists and other physicians. There were differences in prevalence and severity of burnout among practice settings, genders, and longevity cohorts. (orig.)

    To determine the prevalence of hypertension (HT) in patients with Cushing's syndrome. We studied 23 patients with Cushing's syndrome, 17 women (mean +/- SD age = 42.8 +/- 15.6 years) and 6 men (mean +/- SD age = 34.8 +/- 10.2 years). The etiologies were: 16-Cushing's disease, 3-suprarenal adenoma, 2-suprarenal carcinoma and 2-iatrogenic. Blood pressure (BP) was measured at least three times and we consider hypertension when systolic BP > or = 140 mmHg and/or diastolic BP > or = 90 mmHg. The prevalence of HT, at diagnosis, was 73.9% (64.7% in women and 100% in men) and the mean BP was 163 +/- 25/100 +/- 16 mmHg (158 +/- 26/97 +/- 15 mmHg in women and 182 +/- 5/114 +/- 10 mmHg in men). From the 16 patients with Cushing's disease, 13 (81%) had HT; all the patients (n = 3) with suprarenal adenoma had HT; none with suprarenal carcinoma (n = 2) had HT and only 1 of the 2 patients with iatrogenic Cushing's syndrome had HT. After treatment, 14 patients entered remission, 6 persisted with active disease and 1 was missed during the follow-up. In the group of patients that entered remission, the prevalence of HT at diagnosis was 78.5% (n = 11), 57.1% (n = 8) being after treatment. In this study, we found a high prevalence of HT at diagnosis (73.9%). After treatment and in the patients that entered remission, the prevalence of HT remained high (78.5% vs 57.1%). The high prevalence of HT in Cushing's syndrome, suggests its importance as a morbidity factor and also as an important diagnostic indicator, when present.

    Full Text Available Tooth agenesis or hypodontia is one of the most common anomalies of the human dentition, characterized by the developmental absence of one or more teeth. Many studies have reported that the prevalence of congenital absence of permanent teeth varies from 3% to 11% among European and Asian populations. Recent advances in the fields of molecular biology and human genetics have improved our understanding of the cause of tooth agenesis. In this review, we assess the previous literature on prevalence of tooth agenesis comparing the Japanese with other racial populations, and describe the recent genetic studies associated with hypodontia in human and mouse models.

    The chest and abdominal computed tomography (CT) scans of 940 patients were reviewed to determine the prevalence of Bochdalek hernias and to evaluate the widely held concept that left-sided hernias occur more than nine times as often as right-sided hernias. Sixty Bochdalek hernias were identified in 52 patients, a prevalence of 6%, which is more than 100 times more frequent than previously reported. Left-sided hernias were found approximately twice as often as right-sided hernias. The Bochdalek hernia is a much more common congenital anomaly in the asymptomatic adult than previously thought and frequently can be identified on routine chest and abdominal CT images.

    2012-09-01

    Full Text Available A Psicanálise tem como um de seus operadores centrais uma compreensão inovadora da sexualidade humana. O conceito de pulsão e, em particular, o de pulsão sexual possui lugar de destaque. As determinações e implicações dos remanejamentos sofridos por esse conceito na obra freudiana colocam dificuldades teóricas na questão do sexual e de sua relação com a alteridade. No primeiro dualismo pulsional, a pulsão sexual é força disruptiva, oposta às de autoconservação, por seu caráter desestabilizador para o ego. Com a emergência do conceito de narcisismo, a constituição egoica assume caráter eminentemente sexual, e a oposição entre ego e sexualidade é problematizada. Na segunda teoria das pulsões, fundamentada na contraposição entre Eros e Pulsão de Morte, esta última constitui força destrutiva, cuja natureza, para Freud, não seria sexual. Baseando-nos em Jean Laplanche, discute-se como conciliar os aspectos violentos edisruptivos da sexualidade humana com a dimensão de ligação inerente a Eros.El psicoanálisis tiene como uno de sus operadores centrales una comprensión innovadora de la sexualidad humana.

The concept of drive, of the sexual drive in particular, has a prominent place. Determinations and implications of the relocation of this concept in Freud's work create theoretical difficulties in the sexual issue and its relation to otherness. In the first drive dualism, the sexual drive is a disruptive force, opposed to self-conservative ones because of its destabilizing character for the ego. With the emergence of the concept of narcissism, the ego's constitution takes on an eminently sexual character, and the opposition between ego and sexuality is problematized. In the second drive theory, grounded on the opposition between Eros and the death drive, the latter is a destructive force, whose nature, according to Freud, would not be sexual. Drawing on Jean Laplanche, we discuss how to reconcile the violent and disruptive features of human sexuality with the linking dimension inherent to Eros.

    The aims of this study were to determine the prevalence of nutrient deficiencies in patients who present for bariatric surgery, assess nutritional status after surgery, and compare these with preoperative levels. A retrospective study was conducted to identify preoperative and 1-year postoperative nutrition deficiencies in patients undergoing bariatric surgery. The screening included serum ferritin, vitamin D, vitamin B(12), homocysteine, folate, red blood cell folate, and hemoglobin. Results were available for 232 patients preoperatively and 149 patients postoperatively. Two-tailed chi(2) tests and paired-sample t tests were used. Preoperatively, vitamin D deficiency was noted at 57%. The prevalence of abnormalities 1 year after roux-en-Y gastric bypass was higher compared with preoperative levels (P surgery, anemia was detected in 17%, elevated homocysteine levels (women only) in 29%, low ferritin in 15%, low vitamin B(12) in 11%, and low RBC folate in 12%. Mean hemoglobin, ferritin, and RBC folate levels deteriorated significantly but remained well within normal ranges. The prevalence of vitamin D deficiencies decreased, but not significantly. In sleeve gastrectomy patients, mean ferritin levels decreased (P deficiency. Vitamin D deficiency is common among morbidly obese patients seeking bariatric surgery. Because the prevalence of micronutrient deficiencies persists or worsens postoperatively, routine nutrition screening, recommendation of appropriate supplements, and monitoring adherence are imperative in this population.

Bone densitometry was assessed at lumbar spine (L-4) and the femoral neck. The dual x-ray absorptiometry (DXA) scan was carried out in the Nuclear Medicine at King Khalid University Hospital, Riyadh, Saudi Arabia from September 2002 to December 2004. The World Health Organization definition of low bone mineral density was used. Poor oral calcium intake and low level of daily activity were noted. The overall prevalence of osteopenia for the lumbar spine in the whole group was 35.7% while osteoporosis was present in 21.4% of the subjects. In the femoral neck, osteopenia was noted in 38% and osteoporosis in 11.4%. When either lumbar spine or femoral neck osteoporosis is used for diagnosis, the prevalence of osteoporosis rises to 23.5%. Within the whole group, osteopenia and osteoporosis were more common in individuals above the age of 50 than those below 50 years old. Low bone mineral density occurs with high frequency in Saudi men. Lumbar spine appears to be affected to a higher degree. The reason for the high prevalence of osteoporosis in Saudi men is unclear. Possible underlying causes include nutritional, life style and genetic factors. (author)

    In this study, the authors sought to determine the prevalence of stuttering in African American (AA) 2- to 5-year-olds as compared with same-age European Americans (EAs). A total of 3,164 children participated: 2,223 AAs and 941 EAs. Data were collected using a 3-pronged approach that included investigators' individual interactions with each child, teacher identification, and parent identification of stuttering. No statistically significant difference for stuttering was found between AA and EA children. Using the investigator and teacher method of identification, the prevalence of stuttering was 2.52% for the entire sample. For both racial groups, boys exhibited a higher prevalence of stuttering than girls. Of the 3 predictors (age, race, sex) of stuttering, only sex was a significant predictor. AA 2- to 5-year-olds are not overrepresented in the stuttering population for this age group. When data are combined for both racial groups, the prevalence of stuttering is 2.52%. More boys than girls stuttered in this sample of preschoolers.

    2017-10-01

    Full Text Available Published data on the prevalence of autism spectrum disorders point to a significant increase in this indicator. This increase is being studied in numerous publications of analysis, meta-analysis and systematic reviews. The prevalence indicates the proportion of people who suffer at a given time or are diagnosed with a disease. The consequences of the increasing prevalence are relevant from the point of health, social and educational, but especially relevant when as is the case, the cause of the disorder is unknown. It is in this sense that the prevalence study gains importance in order to delimit various circumstances that may give clues to the possible cause or causes that generate disorder. This article reviews studies, summarizes the last data, and reflects on them and possible causes that justify the increased reporting. It looks like these epidemiological indicators can or are influenced by possible methodological flaws behind, which can explain the variations between studies and others. It concludes by stating the need population studies and monitoring that allows us to know the reality of the evolution of these disorders in order to provide reliable information to those responsible for the institutions involved in the detection and treatment of ASD.

    Directory of Open Access Journals (Sweden)

    Denis Jeronimo Svicero

    Full Text Available ABSTRACT: Owing to improvements in animal welfare, such as in nutrition, preventive medicine, and diagnostic tools, older dogs have become increasingly more prevalent than before. Unfortunately, there is an increasing number of dogs presenting behavioral changes correlated with this growth in the geriatric population. However, many of these owners consider these signs as normal for old age. This study aimed to determine the prevalence of clinical signs related with behavioral changes in the canine geriatric population admitted to the Veterinary Hospital of the Veterinary Medicine and Animal Science College of Universidade Estadual Paulista. The owners of 800 old dogs completed a questionnaire about disorientation, changes in social interaction, loss of training (house soiling, changes in the wake-sleep cycle, physical activity, memory, learning, consciousness, and perception. The results showed that the prevalence of behavioral changes in the canine geriatric population was 90.7% of dogs that presented at least one of these behavioral changes, and 22.3% with at least six changes, and with changes in physical activity (58.5% and loss of acquired training (30.2% being the highest percentage groups that were reported by the owners. We concluded that the prevalence of behavioral changes related with aging in the canine geriatric population was high, and that it was important to include questions about behavioral changes during regular veterinary clinical appointments to identify these clinical signs earlier and investigate the possible causes of the cognitive impairment, including neurological diseases, such as Canine Cognitive Dysfunction Syndrome.

  6. Prevalence of Sleepwalking in an Adult Population.

    Mume, Celestine Okorome

    2010-01-01

    Sleepwalking consists of a series of behavioral activities that occur during sleep. These activities may be simple, complex or aggressive in nature. They include motor activities, confusion, and amnesia for the events. Sleepwalking is a disorder of arousal from non-rapid eye movement (NREM) sleep. In children, episodes of sleepwalking are rarely violent; in adults, however, sleepwalking might include violence, which could endanger the patient or others and might precipitate legal issues. There is inadequate information on the prevalence and demographic correlates of sleepwalking in Nigeria. One objective of this study was to determine the lifetime prevalence rate of sleepwalking in an adult population in Ile-Ife, in Southwestern Nigeria. Another objective was to determine the age and sex distribution of sleepwalking among those who have experienced it at least once in their lifetime. A random sample of 228 healthy individuals aged 18-60 years was obtained and the members were asked to fill out a survey form about lifetime prevalence rate of sleepwalking. The overall lifetime prevalence rate of sleepwalking was 7% (16 of 228 participants). It was 10.4% in males and 3.5% in females, but the difference was not statistically significant (p = 0.07).

    Aim. To evaluate the prevalence and possible etiological factors associated with molar incisor hypomineralization (MIH) among a group of children in Jeddah, Saudi Arabia. Methods. A group of 8-12-year-old children were recruited (n = 267) from the Pediatric Dental Clinics at the Faculty of Dentistry, King Abdulaziz University. Children had at least one first permanent molar (FPM), erupted or partially erupted. Demographic information, children's medical history, and pregnancy-related data were obtained. The crowns of the FPM and permanent incisors were examined for demarcated opacities, posteruptive breakdown (PEB), atypical restorations, and extracted FPMs. Children were considered to have MIH if one or more FPM with or without involvement of incisors met the diagnostic criteria. Results. MIH showed a prevalence of 8.6%. Demarcated opacities were the most common form. Maxillary central incisors were more affected than mandibular (P = 0.01). The condition was more prevalent in children with history of illnesses during the first four years of life including tonsillitis (P = 0.001), adenoiditis (P = 0.001), asthma (P = 0.001), fever (P = 0.014), and antibiotics intake (P = 0.001). Conclusions. The prevalence of MIH is significantly associated with childhood illnesses during the first four years of life including asthma, adenoid infections, tonsillitis, fever, and antibiotics intake.
